Another extreme example:No, it wouldn't.
Listen you need some perspective. There was a fellow, I think it was WalkerERP, who had a very particular history with 4ed. WOTC was asked the "WoW" question, and their response was "of course we looked at the most successful video game rpg to see if there was any inspiration we could take from it to enhance and improve our game. We'd be stupid not to". He argued, quite vehemently, that the mere CONSIDERATION of WoW by WOTC meant 4ed was the worst most stupid game ever. Not that the game DID play like WoW, that the mere CONSIDERATION, even if they determined there was nothing they could take from it, was enough to poison the game. It was one of the most vitriolic exchanges I've seen around this forum, and it continued for some time (he was VERY anti-4ed).
And that was merely the most extreme example.
The 4E designers said they briefly looked at MMO-style aggro mechanics, before rejecting them as unsuitable and unworkable for a tabletop game, but they did take an idea away from them (presumably marking or something about how it works). Another user here, RSC, immediately denounced 4E as a game he'd never even consider looking at, merely because, again, the mere fact that an MMO was looked at all somehow tainted it, making not a "real" roleplaying game.
And that's the central point here: for every time there has been a reasonable, good faith "How has WoW/video games affected 4E?", there's been about eleventy billion oneses "4E is just a morepig on the table top not REALZ roleplaying game where lame gnomes weaves baskets like proper D&D!!!!"
