Easy...
Combine the gpu and cpu onto one chip. Move it out from under the dvdrom and put a decent heatsink and fan ontop of it.
Am I hired?
Sure, post a tape-out of the new chip design, and a re-route of all the connections to the separate chips, make it cost effective, and you're hired. Easy.
So if they are hiring now, then that means a new mboard revision is what, 12 months away?
Anyone thinking there will be a 'slim' it would mean ditching the tray load DVD-ROM drive if you wanted the 360 to get much slimmer than it is now. The motherboard isn't that heavily populated or all that large now, it is heatsinks, fans and the DVD-ROM drive that take up most of the real-estate.
