I would think all that would have been addressed by now since SP2 beta also went right on here without a hitch. Even with XP when SP2 and recently SP3 first came out there were some problems seen. Afterwards any needed corrections were seen to.
Once SP2 is final a pair of new SP2 disks for both the 32bit and 64bit editions are next on the list here since the 32bit disk will upgrade a family member out of XP and the 64bit edition will most likely replace XP here soon enough.
