It looks like Blizzard Entertainment could reveal an unannounced game sometime this year.
Kotaku spotted a Blizzard staffer's LinkedIn page, which explains that he's "working on a top-secret project to be unveiled sometime in 2014."
Blizzard's "next-gen MMO" Titan has been rumored as far back as 2007, but Blizzard CEO Mike Morhaime told IGN during BlizzCon 2013 that it had taken on significant changes since its original announcement. Morhaime explained, "we took a step back, we asked a lot of really hard questions about what we were doing and what should we be doing, and I think we've come up with something really great."
Piquing even more interest, Blizzard filed a new trademark last month and posted a job opening for a lead producer for an "unannounced game title."
Whether or not this alleged unveiling relates to Titan, or whatever it may have become, remains to be seen. We've contacted Blizzard for comment.
