We are just 24 hours away from the start of Mobile World Congress, but it wouldn’t be a tech event without a company’s full plan being leaked. HTC is the victim this time. Greek site FullGSM has published photos and information surrounding what looks to be HTC’s upcoming quad-core flagship Android phone, the HTC One X.

As we expected, HTC is planning on a whole “One” device series, which will help them cut down on releases and get back on top. According to the blog, we can expect the HTC One S and an HTC One V to be announced soon as well.

Specs include a 1.5GHz quad-core Tegra 3 processor, 1 GB of RAM, a 4.7-inch 720p display and 32 GB of internal storage. For detailed info, check out the full spec sheet below, and stay tuned for HTC’s official announcement tomorrow at MWC.
