First part of this is not really true, but sure, doesn't usually stop people around here
We'll see what happens when it finally does release, but ALL DEVELOPERS have stressed how easy to code for the Ps4 is so far, a massive change compared to the difficulties 3rd parties had with the Cell for so long. Not to mention the bizarre decisions Sony made with regards to some of their ram/gfx memory in the Ps3 that often left multi platform games underwhelming on their console. Sure, the consoles will be surpassed by things like Nvidia's new Titan gfx card, but the price of a PS4 weighing in at between 300-450 pounds, they'll not be a PC around for a good couple of years that is likely to provide the same gaming specific performance for the price. Specs and numbers only ever tell a small part of the performance story. A massive big people carrier might have a bigger engine than a sleek, lightweight sportscar, but the latter will go faster.
Second part, maybe so, but we'll see what the devs do when things like the new dualshock, wii gamepad, and kinect 2.0 are far more universal in terms of being built into the existing consoles. The weird thing is the Ps3 move was comfortably the most accurate of the motion control systems, but Sony basically gave it no support, and almost let it die. So it'll be interesting to see how it gets treated with the Ps4. Risk is certainly, well, "more risky" so to speak in the current climate, but that isn't to say the indie scene on consoles and Pc isn't thriving to some degree. Creativity is finding it easier to flourish (even including such things as phone apps/games) from small independent developers, but most mainstream game buyers stick to whatever their friend is playing. It becomes almost a vicious cycle. I'd say a lot of the middle budget games that provide fairly high production values combined with slightly more interesting gameplay are the ones struggling most at the moment. THQ obviously going under recently and selling off their IP a prime example of a publisher who had actually released some pretty decent content in recent years, but obviously not made any money when compared to the likes of COD, Fifa, Battlefield... the end.
