according to Graham, the patch 2 (balance patch) is going to include basically two things:
1. the balance changes
2. exe version checking on gamespy to prevent those with incorrect exe file version from joining legitimate games.
I think what Graham said
"We're working with MS at the moment to finalize our patching strategy, so I can't say much of anything about that at the moment because a lot of decisions have to be finalized."
does not apply to this balance patch, it is about future patch plans for T&P, such as the possible patch 3 following the patch 2, etc.
