I believe April was the month the 360 supply constrain ended and started being available on shelves, wasn't it? It fell to about 220k in May of 2006. I don't think we've seen the ceiling for Wii sales, as I have yet to see one on shelves still in the NJ/PA area. I think the 360 could do close to half a million possibly during Halo 3 release, maybe even edge out the DS Lite that month.
