Rumors - and we stress, RUMORS - from QJ.Net regarding the March issue of OXM claim that, among other things, OXM reports that:
"An update for Rock Band that will make band world tour playable online"
Also of note:
"What's interesting to point out here is that OXM has apparently given DMC4 a score of 7.5, while giving The Club as score of 8.0."
If this is true, it'd be reassuring news for those who thought that we may have to wait for the inevitable Rock Band 2 before we could play in a World Tour with friends on the other side of the country.
