No dice at the Orange, CT Bestbuy. I had the associate look up both PS3 SKU's in the system, and neither showed anything in stock. I asked if there were any defective PS3's which might be showing up as inventoried items, and he indicated that they haven't had a single return (probably because nobody has actually opened their systems yet). Sucks.
However, I was able to score a memory card adaptor at the local Target. I'm envisioning that these things are going to be in pretty short supply, so you guys might want to check 'em out.
