I consider the D3 playstation gag to be far more of a joke than hearthstone, give D3 players alot of what they have been screaming for with the punch line "lul but its on PS4"
I am very looking forward to hearthstone, a light hearted f2p card game I can play to relax.
Game looks pretty good. Much better than MTGO. Going after the CCG market is a smart move by Blizzard. They got into it a bit with WOW TCG, but they had a partner and it never gained the popularity that MTG has. Give than MTG is on their 20th anniversary, it's proven that it's here to stay for the long run. By releasing a computer version of a CCG (kinda like a mix between DotP and MTGO), they are going into a new market that relies on their expertise of release software products using an IP that everyone loves (Warcraft).
Honestly there isn't much point to having left this open anyway. It isn't a joke, it isn't an April Fools joke, and there isn't anything to discuss about that.
