Dev costs shouldn't be a problem going into next gen. Assets are generally produced in very high resolution and are ported down, plus most multiplats on PC already look like the next gen demos that Sony has shown off. Just compare the console versions of Crysis 3 or even Batman Arkham City to the PC versions. Yet the costs are identical. Plus, coding on PS4 should be much easier than PS3 due to the PC-like nature of the console.
Pricing on the other hand could be a problem. The console is relatively advanced and appears to be bundled with a new Playstation Eye. Microsoft have enough money to price the console competitively whilst Nintendo already have cheap hardware and will likely drop the price. Having said that, lack of thrid-party support will probably hamper growth of the WiiU whilst PS4 and 720 will have to compete head-to-head on pricing.
