HTC put on a big show during CTIA Wireless 2011, and it looks like it’s taking the show on the road. On Thursday HTC began sending out invites to European press urging them to come “see what’s next” on April 12th at 1:30p.m. GMT in London. We’re not sure what HTC has in store for the event, but we wouldn’t be surprised to see it lift the curtain on a European model of the EVO 3D, which is launching on Sprint in the United States. Most every other new announcement during CTIA, including the Flyer, was already revealed during Mobile World Congress. Perhaps we’ll see a brand new device ‚ÄĒ HTC Pyramid? A new Windows Phone 7 handset? Stay tuned on April 12th for our coverage of all the action as it unfolds.
