Everybody's saturated with the marketing hype of next-generation consoles. They are wonderful, but the truth is that they are as powerful as a high end PC is right now.

Sure, any given feature list can be implemented, given enough coding time. But in addition to coming out late, you will usually wind up with a codebase that is so fragile that new ideas that should be dead-simple wind up taking longer and longer to work into the tangled existing web.
