I believe PS4 Neo users will more likely to get fuck over because most most dev will not use the power of PS4 Neo.
But if they sold at $399, that will soften the blow, cause UHD blu ray drive already justify the cost.
I bet Sony first party will have Neo improvements for all games (Ratchet & Clank at 60? Probably not doable :/), third party not so much. Maybe slightly better framerates but that would be it.
Another question is will the bumps help they do ps3 emulation in any way? I assume not (and they probably aren't interested in it).
