Blizz will never let anyone push them into releasing an "unfinished" game. And TBH, if someone thinks WoW is "bad", they didnt play the other MMORPGs yet.
(btw, Bugfixing and balancing probably takes longer then the initial development)
I think mainly people that played other MMORPGs before think WoW is "bad" (including myself) How can you call something bad if you cant compare it to others Games you have played? (Everyone should know that MMORPG "Reviews" basically say nothing about a Game)
Iam not saying the other upcoming MMORPGs are better than WoW though :P
Blizzard announced WotLK for the fiscal year 2008. My wild guess is late Novemeber/start of December.
Looking at the Beta I dont really think it should get release that early, but with WAR getting released and lots of the WoW players being eager to find a new MMORPG that isnt as "bad" as WoW I think the bean counter division will push them to release it to early.
And besides Bugfixing and Balancing WotLK is finished besides the obvious post cockblock bosses raid instances (Hyjal/BT alike). Its possible to get it in a "releaseable" state but I think they should take their time to bring out a good product even if it means that some k players quit the game out of boredom :P
Because the client base is virtually the same of course...
I think the percentage of people running AdBlock here is quite high and the usual person is not Browsing this Page hes Downloading AddOns he got referred to by others or browsing the AddOns, almost nobody will click the Ads.
And afaik Curse is not displaying Gold Seller/Power Leveling/Exploit ads/etc. if that didnt change so far(I dont visit curse normally and run Adblock/noscript), so the only Ads that idiots would click wont get displayed anyway.
I dont really see the problem in the Client gathering non personal system information.
Those information you already made available anyway:
WoW collects and submits "non personal Hardware Information"
almost every other MMORPG does it aswell
Steam does it and even publishs Studies about it which are really important even for every(even non steam using) publisher
Every bigger Websites does it if possible
I dont really see a bad thing behind it. Websites have to be financed, the amount of money by ads raises if you can specifiy what User group are viewing your content and the AdProvider can specifically provide Ads targeted to the consumers. Even projects generously hosted by someone(lets say Google) have "hidden" ways to finance themselves, almost always by gathering statistic Data for the given Hoster.
Aslong as they dont start to gather personal Information its not really a bad thing.... You could argue that starting to gather such information ends in gathering Personal Information by checking which URLs are browsed etc., but I dont think in this community this would be done long...
