i heard this news about a year ago from microsoft themselves they also leaked a possible redesign of xbox. i can't believe people don't remember the news
*Gasp*, will they really use a Heatsink and a **FAN** on the CPU? Wow, apparently they realized something like "oh crap, passively cooling a hot triple-core chip might not be the best of ideas."
It all may be educated guessing at this point, but it makes far more sense for Microsoft to bundle in $100 hardware at no added cost rather than drop the current $299 SKU to $199.
