Discussion in this thread has drifted a bit off topic, but I wanted to chime in to respond to some of the questions raised on the first page. Sorry for the delay in responding, info is moving slower with many of our partners out for the holiday.
Country Track Pack Vol 2 is based on the RB1 engine, same as all previously released track packs.
This track pack will be exportable, and as with all past track packs the current plan is to release these songs as DLC at some point down the road.
These songs should have harmonies and Pro drums available upon export (but not when played off the track pack, as it is based on the RB1 engine).
At this time we do not have any plans to release RB3 Versions or further Pro upgrades for these songs when they are released as DLC.
Hopefully that clears up some of the confusion and reassures you that the track pack is still a worth while addition of awesome country tracks to your RB library.
I guess things change.
Who do I have to get drunk in order to get "Red Solo Cup" in Rock Band?
