A quick google search of "Heroes of Warcraft" leads to articles mentioning that Blizzard is attempting to get the domain "Heroes of Warcraft", or atleast tried to November 2012 http://www.eurogamer.net/articles/2012-11-20-blizzard-swoops-on-heroes-of-warcraft-domain
I googled it because I was reading about the creation of WC1 (http://www.codeofhonor.com/blog/the-...arcraft-part-2) when I stumbled across this:
"Briefly, Warcraft III started out as a game called Heroes of Warcraft, which departed from the type of traditional RTS we had already launched five times before (W1, W2:ToD, W2:BtDP, SC, SC:BW) and was instead a squad-based tactical combat game set in the Warcraft universe."
Any speculations???
