Just went to a Best Buy (Alabama):
0 wii
2 Xbox360 (both arcade)
Dozens of PS3 (40GB)
Uncountable PS2 (I counted 15 in one area, then went to the PS2 aisle and decided there were too many to matter)
0 ds
8 or so PSP
No Xbox360 CoD4 (Doh!)
8 NMH (I grabbed one)
Tons of Rock Bands (20+)
No other shortages that I could see
