<p>We’ve heard a few times that there are going to be 2 version of the upcoming high megapixel camera, one with a low pass filter and the other without.  Nothing has changed on that front, as we continue to hear that will be the case.</p>
<p>We’ve been told a few times that this is coming in the first half of 2015, now we’re hearing the cameras will be announced in March. So by the sounds of things, don’t expect anything high megapixel related at CP+ in Japan next month.</p>

I gave up waiting and bought a 645z

Don't hate me.
There is no reason to hate our friends who practice polygamy.

If I needed 50 megapixel at this point, I would also choose Pentax 645Z for those images that do not require agility and portability. For the other types of pictures I like Canon, apezar of sensors that look backward.

Explanation please? What is a low pass filter in this context? What is it for and if it's necessary, why build a camera without one? Is it the same as an anti-aliasing filter (another term I don't understand...)
Yes, they are one and the same thing.

Yes, the low-pass filter is the same as AA filter. These filters aims to avoid moiré and aliasing, which occur because of the repetitive format of pixels (all the same size and shape).

In ultra-high resolution cameras with low quality lenses, the AA filter does not lack. But put a razor sharp lens, as Sigma 50mm Art, moiré and aliasing will be visible. I'd rather have an AA filter and not worry about jagged edges and false colors in my images.

Will this be the first time Canon comes with two versions? I so doubt this….

Not really, they've made a few 'a' models especially suited for astrophotography. Compare:

So I guess my question would be why would there be two versions what are the advantages of each I confuse easily Thank you
If the objects in focus in the image NOT have straight lines, and has NO repetitive geometric shapes, the AA filter is not required.

A camera with no AA filter, using a high sharp lens produces images that can be printed in very large sizes while maintaining sharpness. But objects like fabrics, screens, grids, and other highly subject to moiré can ruin a photo without AA filter.

I remember talking to a rep at the show about the 60da and i was going to get one due to its sensitivity level vs the 60 but never bothered this looks like the same trend these 2 bodies will have and one will be cheaper i am guessing.

I understand what your saying here about the AA filter that's great info to know but saying it will ruin a photo without the filter is a little over board here, im sure there's more to a photo than just a filter pass, it's good to have it if one can but it's not that serious. so many great images out there without this filter in camera's but I get your point here on the advantages of having one in the camera. Thanks.
