Why will they be in a lot of trouble?
I'm sure that all the CS:S players out there were really unhappy when they fixed the %n crash or any of the other patched exploits/crashes.
I'd rather they patched these kind of bugs as soon as possible, even if they run a higher risk of one day introducing problems with one of their patches. It's not like we've never waited months for a patch for other games, only to find that it fucks something up.
Oh well, some people will never be happy until games are release bug free. Happy waiting.
