It was shown during sonys press conference at e3 right?
Oh wow you're right!
Anyhoo, It is hard to predict what any of that will do. Halo will sell a bunch of copies, but it's not Halo 4, 50$ cut at an already more than affordable price, slim isn't much of a difference...Natal is the key to all of this. It will be interesting to see what happens, but it's not like that collection of things is a powerhouse, it's just a collection of things.
A price cut is always a powerhouse. The last one is 18 months ago (except the $50 one olny for the elite and only in NA).
A redesign is always a powerhouse, look at PS2 slim, PSP 3000 (not the Go lol), DS Lite, PS3 Slim. A redesign 5 years after release would be perfect.
Natal might be a powerhouse.
But you can bet that MS will spend millions of dollars to let everybody know that there is a redesign, a halo, a Fable, a price cut and Natal. If this really happens (I have no doubts to be honest) MS will make the biggest marketing push in this industry.
There once was a great sig here, but it got killed.
A moment of silence would be appreciated.
