When will Microsoft exclusives be reviewed?

[Zappykins]

It's a bit like a movie.  The reviews come out right before the launch.  They want people excieted and talking about it.

And that is why people go to game shows, play games, and write reviews and reports about what they saw. 

Few examples: 

We already knew that there were frame rate issues, particurally for one console, from E3.

Whe knew Dead Rising 3 got improved between E3 and TGS and GamesCon.

Motion triggers for Forza weren't on at Comic Con, but later were at GamesCon.

Fomr the TGS that Knack was having problems.

The list can go on, and on, but these early tries at a game are really imporant for people to get a heads up information.
