From what I've seen:
The OTC Role-Play lightsabers have turned up at RETAIL (Target/TRU).
The OTC Vehicles (X-Wing & TIE Fighter) have turned up at a few retail locations and most on-line shops (EE, Kebco, etc), all little guys who got stuff from Hasbro. No signs at the big three yet...
The OTC figures have NOT been "confirmed" at retail yet, as far as I know. None of the big sites is reporting it, and if they were out, someone would have a figure w/receipt pic.
The order on figure timing usually goes like this:
1 - EBay Auctions from Asia
*2 weeks pass*
2 - Asia Based On-Line shops start selling the figures
*2 weeks pass*
3 - On-Line scalpers er... Price Gouger er... "High Demand Product" On-Line stores get them (Action-HQ, Brian's Toys, Cloud City). These are the stores who pay a crapload to have the items air-shipped from Asia.
*2 weeks pass*
4 - "Regular" On-Line stores (EE, New Force, Kebco, etc) start to get ship notification and/or the figures start turning up at the Big Retail 3 (Target TRU Wal-Mart).
This pattern has held pretty true for some time, with minor variations for shipping problems, etc. From the first auctions we see from Asia to Retail stores is usually 4-8 weeks.
Given that we are just hitting about 4 weeks since they turned up on eBay, I'd say that they realistically could start hitting Target/TRU/Wal-Mart any day now really...
