It comes down to this for the indie developers:
A.) Sell to as many people as possible on every platform possible, conforming to the lowest common denominator's limitations and contractual restrictions if necessary.
or
B.) Make the game THEY want to make and sell it on the platform that supports THEIR OWN vision, without compromise.
-Most people will wisely choose (A) so they can actually make a living off their own work.
Sucks, but that's the way it is.
Ah, that happens sometimes. But mostly Indies continue to be a hotbed of innovative ideas and niche genre revivals, and PS4 just ends up getting a shitload more exclusives. There are plenty who do contort to it, but many are fighting back as well.
