I gave up on WC4 years ago. WoW is what Blizzard intends for the story to progress and it brings in insane ammounts of money, not comparable to what an RTS would.
However, I'm still very excited for a WC3 remake, as it seems realistic and experiencing the campaign for that game with more recent tech, mechanics and graphics would be wonderful. Bonus points if they retouch the old Cinematics aswell.
