Neglecting crpg dicourages people to play it = less new players; less current players = less people moving swiftly to M:BG.
Does it, really? Patching few things would surely help but I have a feeling that support for cRPG ended a long time ago and that recent few patches, including famous revival patch are something extra cooked by player-devs.
If you ask me why I still play cRPG despite the fact it is broken in many ways and make less sense than ever, answer will be that I'm still having more fun than I have with other games my "rig" is capable to run. That probably goes for most of still active players. At this point it is borderline masochism, but alternatives such as native aren't better overall.
chadz said 3 months, even though I have a feeling that will take at least a year, it still isn't that bad because we have already waited for quite some time. And it's not like there will be no great games to keep you busy till then.
