I like improvements in graphics and processor power as well. And the industry has a very fast pace as it is. But when you push too-far-too-quick, there are consequences, and mainly that consequence is money. Personally, if Sony had waited a year, reduced the price to about $400 and by-then would have had rumble back in, the console would appear moderately more appealing to me. But personally I'll never pay more than $300 for a video game machine, no matter how many extra features it has.
Nobody is crazy enough to accuse me of being sane.
