Using the time between going gold and ship date to add finishing touches to the DMC. Sounds like a smart move.
I had minimal issues with both. K1 was already patched when I got it, but I had no real problems going through K2 unpatched.
Both had gamestopping bugs on the Xbox, apparently - which, obviously, no patch could fix.
