I'm sorry, but this has FLOP written all over it..
First of all, it's a console add on, and we all know how these perform.
Second, it's already PROVEN that it can't do everything MS claims, it'll be a glorified eye toy.
3rd, where are the games?? Seriously, not a SINGLE game shown thus far! It'll either see massive delays, or it will come out when they say it does, and the games will be highly rushed and be terrible quality.
I will gladly eat crow if I'm wrong, but this product has all the makings of a financial disaster, and/or disappointment in terms of what it can do.
