According to Judgehype, Blizzard Entertainment added some interesting files to the Battle.net Launcher in the latest update. Among those files are images of the Warcraft III Arthas splash page for the Launcher, and the game icons.
If this was true, what are the chances to see StarCraft and Diablo II on the Launcher? Possibly good ones. However, Blizzard hasn’t made any official statements at the time of this posting.
Thanks to staff member, Lugia for the heads up.
