I was wondering that too, it's freaking identical to the 3 i have here at the house. I stopped buying them as every year it's the same 80 games, it's that way with the handheld too. Maybe they put a sd card slot in it? It's the 25th Anniversary of sonic so maybe that has something to do with it but it looks the same to me. The sd card slot would be good, the handheld has it so you can add more games and it runs and emulator. The one thing the sega has over nintendo is you can use your old genesis carts in the thing.
Edit: @
Moviefreak They updated that link you posted and admitted they'd been fooled, it is the same system that's out there already.
