It just goes to show that if you throw enough darts, eventually you might hit your target. What Pachter says sounds entirely plausible. I see no benefit for introducing the slim model by itself and then Natal. It'll appear together as a standard package to drive Natal into the market. $299 is also possible given that we've seen the Arcade edition for 160-180 on sale. Add a 250 GB drive for about $60 OEM price without the added external package for current 360 and about another $70 for the Natal camera and about $30 cost savings by switching to Valhalla you get $300 for the package.
