yeah theyve talked about it, of course theyve talked about it. wow is the most profitable video game OF ALL TIME. only idiots wouldnt talk about it.
however theyve said time and time again that wow 2 would essentially be worthless and until wow has run its course its not really a good idea and they arent gonna do it.
history has shown that mmo sequels just dont work out well, they cannibalize their playerbase splitting it between two products essentially doubling production costs and time with little profit.
mmos also take a VERY long time to make.
wow still has 6 million subscribers and its still making roughly the same amount of money it was back when it had 12 million subscribers because most of the lost subscribers were from china and the cash shop has made them millions.
will there eventually be a wow 2?
yes, when wow 1 is on its last legs and is dying. if they even want to make a wow 2. maybe they will want to make warcraft 4 at that point. wow is the most profitable game of all time, thats like asking is there gonna be another pokemon game? of course there is pokemon is the 2nd best selling video game franchise of all time.
however speculating about a wow 2 at this point in time is pointless and stupid
