If this turns out to be true, this is likely the push I was waiting for to jump onto Xbox bandwagon.
I've already own Wii & PS3, and decent PC. Though 360 seems to have its own interesting line-ups, not quite to the point I was willing spend extra $200-300. Especially when I already have Motion Game Console & Supposedly most technologically advanced console.
But with Natal, I felt like 360 is getting more unique and interesting. Natal > Wii in the motion technology-wise.
With additional hardware upgrade on 360, the difference between PS3 and 360, which appears saddle, may change their relationship i.e. New 360 full power > PS3 Or at least equal to that of PS3. If they becomes equal, then 360 is the winner in this regard as 360 is much easier to develop for software companies.
So in conclusion, 360 to me sounds like going to become the best of the best console on the market if they really do what 1 up says to do. And indeed this may be the last push MS need to make their console a primary choice of the console. Well, at least I will be convinced to say 360 is my choice!
Oh and it's really clever for them to do this rather than releasing brand new console from scratch. A. less R&D. B. Current owners of 360 is less affected. C. Yet, MS is providing option & way to allow developers to match up with PS3 potential power OR even exile it.
