How about some efs primes canon..

Apparently the EOS-M is for the true enthusiasts who love primes, and EF-S is for slow zooms for soccer moms and hockey dads.

I kid. 

EF-S people have every right to feel abandoned here.  Other than macro or pancakes, EF-S doesn't get primes, apparently.  At least not from Canon...

It's own little plastic STM trinity you mean. 
Stubbornly, as a stills guy, I want better built, internally focusing USM lenses for this platform.

I find, the current EF-M lenses have surprisingly good build quality. If future primes are built like the 22/2.0 - i.e. metal mount and "metallic" shell with very tight and nice build - it would be totally unwarranted to call them "plastic trinity". I am hoping for EF-Mini Size, Mini price prime lens set ... including a super compact EF-M 80/2.4 STM IS, optically on par with 22/2.  :)

STM AF drive is actually better suited to mirrorless hybrid-AF systems than USM, whereas Ring-USM AF drive is better for stills photography with mirrorslapper phase-AF and big, fat lenses with massive glass elements to be moved.

Personally, I'd much prefer EF-M lenses with AF only - without focus ring and no manual focus gear. Savings in production cost to be applied towards full weather-sealing. 8)
In conjunction, upcoming EOS M4 should also be fully weathersealed. After all, EOS M is my ultra-lite outdoor/alpine mountaineering/backcountry skiing gear. :)

A 15mm EF-M = a 24mm prime in FF.  Lovely, but who the hell was asking for this?

Me! Me! Me!  :)

15/2 sounds interesting, could be small and nice. I hope they will make it without big barrel distortion.

Wit 15 and 35 primes there are enough options for M <40mm, but Canon we need telephoto lens too.

It would be a pity if after updating most of their EF primes to include IS, that they now revert back to offering non-IS* primes in EF-M

The M system will have a distinct disadvantage compared to other MILCs that have IBIS and hence can have small sized primes but still offer IS

*not that we know whether these have IS or not

Yes, Canon seems to be determined to not offer a fully competitive mirrorless system any time soon.

Leaving out IS on EF-M prime lenses would [only] make sense, if EOS M4 and future Canon EOS M bodies came with Sony sensor units including "5-axis" IBIS.  :o :D

Even last gen Sony sensor tech and AF as in A6000 would already be a major upgrade to Canon's current EOS M ecosystem. Such a Canon APS-C MILC would be pretty much, what i am after: body not bigger than EOS M3 or Sony A6000. Built-in EVF in left top corner, not G5X style "humpback" please. Better AF, IBIS, Canon UI, Canon RT flash transmitter built in ... along with optically good, compact and highly affordable EF-M lenses.

It ain't difficult, Canon! :)

I wonder how does Canon's DPAF compare to, for example A6000's AF system?

IMO it should be really obvious choice to Canon use DPAF in mirrorless body.  ???

The zooms have IS if that's a key feature for you.

I'm not sure who really needs IS in a fast wide prime on a camera that can do a clean (enough) ISO 3200. Are you shooting astro handheld or something?
It stands to reason that the vast majority of users would rather have a smaller size, lower cost, and higher optical performance of a non-IS lens.

EF lenses are different. They are already larger, so the IS mechanism isn't as much of a compromise.

I feel the same. I'd rather have the smaller, cheaper, one less thing to break, non IS lenses on the M. Always a compromise. And adding IS, if it doesn't make it bigger, more expensive, then something else has to go, smaller aperture possibly.

IS in the zooms is probably a good compromise. One they are already bigger lenses so the whole "I want the most compact kit" is already out. And since they are slow lenses, adding IS is probably much easier with such a small aperture.

Short answer:  IS is for reining in high ISO usage in poor light.

IS simply equals speed when you are running out of light (and the subject isn't moving).  I'm shooting primes handheld at 6400 on my 5D3 all the time, and IS would let me walk that down to 800-1600.  That's huge.

We have a bit of a cavalier attitude that sensors can handle anything from a noise perspective these days, but even on the great 5D3, despite manageable noise at high ISO, the color and DR goes to hell up there.

How about some efs primes canon..

I'm in this camp, too. The weight of a 7d body doesn't bug me, so I'm unlikely to go mirrorless anytime soon, but I've grown to like the size/weight of the EF-S 24mm pancake over the 17-55... but I'd much rather have a few more options, and I think an EF-S 15 would make a nice complement to the likes of the 28 f/1.8 / 35 f/2 IS (normal on crop) and the 85 f/1.8 (135 equiv.) to give a nice trinity for EF-S...
7D x2
70-200 f/2.8L - 17-55 f/2.8 IS - 10-22 f/3.5-4.5 - 85 f/1.8 - 50 f/1.4 - 28 f/1.8

they aren't going to be that dramatically different in size to the already existing 35/2 40/2.8, 28/2.8 options, 24/2.8 options that already exist.

for instance, canon's 35mm 2.0 IS USM is 77.9 x 62.6 mm the nikkor DX 35mm is 70 x 52,5 mm with no IS.

it's not that easy.

you still run into the fact that your shutter speed is simply too long.

any sort of motion you're limited to 1/focal approximately anyways to combat motion - or higher to around 1/60th of a second.

the only time IS and wide angle and low ISO come into handy is interiors such as churches museums, architecture etc .. things that don't actually move.

What part about the above was incorrect? 

There are far more 'things that don't actually move' than interiors, and IS helps me capture them with a far lower ISO than if I didn't have IS, plain and simple.
