Very weird. Just checked my local stores and...
1) Gamestops
PS3: none have PS3 120's OR 250's. 10 local stores.
WII: All sold out as well
360: 2 of 10 sold out on Arcade. 1 sold out of Elite (they do not overlap)
2) Bestbuy
PS3: no 120's and no 250's (cant even do a store check on the 120s) 6 local stores
WII: 2 of 6 sold out of WII.
360: All 6 stores have both SKU of 360 available.
3) Target
PS3: only 1 store with 120's/250's (tho says low availability). 10 local stores.
WII: onlly 1 store with console (exactly the same low ava in one store as ps3)
360: 2 of 10 stores sold out of both SKU. 1 store sold out of only Elite.
Very weird. I live in Raleigh, NC just for completeness sake.
