During Blizzcon 2013, World of Warcraft production director J. Allen Brack revealed that a small team was working on updating the old Warcraft games to run on modern PCs. The first hints of these updates might have been spotted in a recent Battle.Net Launcher update.
MMO Champion spotted that the update added a background image and a few icons that are all recognisably from Warcraft 3. The artwork is at the same resolution and dimensions used for other games in the launcher, suggesting it’s being uploaded as part of a new playable game in the launcher
"So, we actually have a guy on our team — actually several guys on our team — who are actually working on a side project to do something like that in some form or fashion," Brack said back in November 2013. "We're fans of Warcraft 1, Warcraft 2, Warcraft 3, and we'd love to replay those games for sure."
These files don’t mean a release is immediately incoming but with BlizzCon 2014 taking place next month this could be a sign of an announcement at the convention.
