I'm not an expert either, but i've seen some results from the Red one, and that looked good

4K is a lot of pixels, and it's out for a few years now. Yes, their pre-announcing is annoying every now and then, but on the other hand, Canon sometimes surprises you with an upgrade just after buying their now-dethroned champion... We can just hope that Red gets its production lines running smoother over time, and that they keep things as modular as they are.
Yes, they do count their pixels in odd ways, but 6K is at least 6000 pixels horizontally, and even if they use very wide sensors, that still makes them 2500 pixels high, giving them 15 megapixels. With APS-C that puts em straight into Canon country.
I feel the RED products that are in the same resolution range as video-capable DSLRs are in trouble, because the DSLRs have volume and (almost certainly) price advantages over the RED products.
They do have the volume advantage, but they're still cameras tuned towards video, instead of the other way round. Red has shown already that they just want to make a good videocamera, and they have no high-end business to protect. How long did it take Canon to implement 1080p 30fps on their DSLRs, while every pocket camera could do so easily? The knowledge was there, they could've put it in the 30D if they wanted, but they didn't. That's what frustrates me every now and then, so i hope Red, Sony and some others stir this market, so soon everyone has 4K+ in their camera, and we can pick one that suits us.
