HTC plans to announce something exciting at MWC today – the long rumored HTC One X and HTC One S, also known as Endeavor and Ville, respectively. In fact, the Taiwanese have been literally counting the days to their Sunday announcement. But, as it so often happens, somebody had to come along and ruin the fun for HTC.

Yesterday, Marco Polo, an Italian shopping site, briefly listed One X and One S for sale, complete with specifications and images. Actually, as The Verge reports, the two devices were posted under their previous circulated codenames, Endeavor and Ville, which adds to the confusion that built up over the last weeks.

But the cherry on top comes from a Greek tech site that posted images and full-specs of One X, leaked from what seems to be an official HTC release.

HTC One X Specs

The biggest news: HTC One X will run on the Tegra 3 4-Plus-1 architecture from Nvidia, with 1.5 GHz clock-speeds. Other specs include Android 4.0 Ice Cream Sandwich, 1 GB of RAM, and an 8 MP camera. These specs fall nicely into place with the specs leaked on the Italian shopping site and reported by The Verge.

Here’s a full list of specs, courtesy of FullGsm.gr:

• 9.29mm thick
• 130g in weight, battery included
• 4.7-inch Super LCD2 screen, 1280 x 720 HD resolution, Gorilla Glass
• Quad-Core Tegra 3 processor
• 1 GB RAM
• 32 GB internal storage
• Free 25 GB of cloud storage from Dropbox (for two years)
• 1800 mAh battery
• 21Mbps HSDPA radio, quad-band
• NFC-enabled
• Wireless HDMI, DLNA
• 5-pin Pogo Pin connector
• 8MP rear camera, LED flash, 1080p video recording,
• 1.3MP front camera
• Beats Audio

If you’re wondering about the price of this baby, it’s €699 with no contract or about $935. You asked for it…

HTC One S and One V also coming

For HTC One S, we don’t have yet the full spec sheet, but judging from the Italian leak, the One S will be quite similar to One X, except:

• Dual-core processor instead of the One X’s Tegra 3 quad-core
• 16GB of internal storage instead of 32GB
• 960 x 540 resolution instead of 1280 x 720

The price of the One S will be €599, or about $801, without a contract.

We also expect news about the One V, a smaller, cheaper device, heavily oriented towards music lovers, to become public soon, too. The One V will probably sport a dual-core 1Ghz processor, a 3.7-inch screen, and 1GB or RAM. The device will feature its Beats Audio integration prominently (HTC is a partial owner of the Dr. Dre-styled brand).

More details as they come

HTC will launch the One S, One V, and One X later today. Our guys are on the MWC floor, ready to fill us in with the latest news, so make sure to check back soon!
