Microsoft comments on lack of new Xbox 360 exclusive IPs

[Reasonable]

Wow this turned out different than I expected...

Personally I do prefer variety over the small number of sure thing "blockbusters" mentality but given 90% of each consoles library is 3rd party the exclusives are really only a small element of differentiation (TBH as a dual console owner I find the PS3/360 to essentially be kissing cousins in most regards) and one that's down to personal preference.
