News is coming out that Rock Band may be a timed exclusive for the Xbox 360, an announcement which is sure to aggravate many PS3 fans.

Promotional material is leading sources to make this claim as the latest promotional material has no signs of a PS3 logo anywhere as only the Xbox 360 logo is showing.

This could have been a marketing error or it could be a bigger story in the works as E3 is only one day away. Is it possible that Microsoft could have literally bought another huge exclusive for the Xbox 360 with Rock Band or will it just be a timed exclusive?

Here is to hoping it was just an error and they forgot to put the PS3 logo on the promotional material for Rock Band. Until E3 though we will not have anymore infrmation.
