You are very wrong if you think next gen games are necessarily much more expensive than current games. Do you know what costs a lot of money? Optimization on old hardware. Faking visuals to achieve a certain look. That costs money. Assets are already produced in very high quality. The workflow will not change drastically. You have less limitations with new hardware, and if the new consoles from Sony and MS really are as similar as some rumors suggest, multiplatform games will be even cheaper to develop. And that's the problem with the Wii U: It may be simple to port current gen games to the Wii U, but it will be difficult and expensive to port next gen games to the Wii U. And Budgets won't make drastic jumps - they are getting bigger, but only because the gaming market grows.
