I think it will, however whether that number is significant is another story.
I think their purpose in creating a new game was ... a new source of revenue?
Yes, yes it will. And not just WoW but other Blizzard games as well.
Hearthstone is a great marketing tool for Blizzard. They are able to attract a new market segments to battle.net, which then allows Blizzard to effectively promote their products (Remember, Battle.net Launcher?).
It will most likely attract a small base of players, however the reason behind creating this game feels more like an attempt to cover new ground (both the F2P genre and the Digital Card Game Genre) considering the momentum both games like Shadow Era & Scrolls have amassed.
But if we're going into what the purpose theoretically behind this game is, and lets say that it is to attract more players to WoW, i'd think that the part of the playerbase (that doesn't know who the characters really are) will most likely just google around and read wikipedias around them, thus negating the main "purpose" of the game.
Still, it will be fun as h** to play it
For some people yeah, for the majority? Nah.
It have some similarities with WoW but it is in a different genre so it will attract a whole new audience.
It will attract millions once you get cross-game rewards from wow to hearthstone to wow.
On battle.net launcher, I LOVE IT. Been using it since I heared about open beta. The thing I never thought of needing.
for 95% of players who try hearthstone that never played wow, I would say no as it is a completely different genre. It will however give blizzard a nice revenue bump, and anything that helps blizz stay afloat so they can keep making wow, I'm all for.
I doubt it the two games are in completely different genres.
If there are people who will play WoW because of HS it will probably be a few thousand, but nothing to big.
I can't speak for other people but I can for myself, so no. And assuming I did come back, it wouldn't be because of Hearthstone.
idk. maybe some but i dont see the ipad crowd being into computer games theyre to busy with their angry birds and their 2 dollar mini games to take the time to sit down and play an mmo.

I think it'll bring very very few players.
Let's face it, everybody and their dog knows about WoW, particularly people who are into card games are the type to know a lot about the gaming world.
I think Hearthstone will be very successful though
