Ok, using VGC numbers, from Sep-Dec 2008, the 360 outsold the PS3 WW around about 2,051,000 units. From Sep-Dec 2009, the PS3 outsold the 360 WW around about 2,167,000 units. Both of the increases were after pricecuts that the other didn't have.
That's the only point that I was making. They are EXTREMELY comparable. Holiday 2008's 360 performance didn't doom the PS3, so why would this one doom the 360? It doesn't make sense. These numbers reflect the trend of a price cut, not some major change in the market.
