well guitar hero 4 definately worth waiting as it is not a ripoff from rockband...its drums has 5 colours and more realistic with 2 crash cymbals unlike rockband...plus u can record new tracks..just cudnt wait...
im an owner of guitar hero 2 and 3..going to get either rockband or guitar hero 4...u can have one playing the bass and another friend playing the guitar..Plus it is an amazing collection too..
im an expert player....maybe it will be cool to have a tournment or jamming session with guitar hero or rockband..
