Do you think ML could do MJPEG at S1 (2880 x 1920) on 5d3?

MJPEG is very good at high bitrates, it is at low bitrates that the newer codecs pull clearly ahead

I doubt Magic Lantern will go so deep into the image processing: with previous cameras, ML has been great at adding features, improving usability, providing monitoring tools, etc, but it has never been able to improve the image processing. ML mostly lives in the ARM side of the digic processor.

So, if the new encoder has a couple of parameters that they can change to get a better image, it will be a great win. But if that happens, it will probably be still IPB or All-I, not a new codec.

agreed. ML has its limits. It is more of a tweaker than a re-write. people also forget there are bus speeds, data path widths, read-out patterns and processing baked on chips which aren't firmware modifiable and are the real limits on top of the complexity of dealing with something as custom made for hardware as camera firmware. These are not general purpose PC's with OTS hardware. ML simply won't get 4K out of that camera the way canon could if they had set out to do that. If it was as easy to improve the quality as setting some parameters in some functions, canon may have just done it themselves. Not to say there isn't room for improvement and maybe higher bit rates but a higher bit rate is only going to help reduce codec panic in motion and not really improve quality since garbage in is garbage out.

I think the best thing for the ML guys to do is try to go for uncompressed clean HDMI. In that way you pick whatever codec you want and whatever bit rate it pleases you. The video won't be any crisper, but at least it will let you bypass the internal codec's mess.
