Well it seems the jolly ol folks in the UK have gotten Xbox 360 fever.  Sales for the 360 have jumped 260% over the last two week according to ChartTrack (UK version of NPD except they don't publish their numbers).  It probably doesn't hurt that BioShock and the Xbox 360 Elite (with the price drop) came out over that period.  That's not bad considering we are looking at about a 158% sales increase in the US since the 360 price drop.
