HTCLast week we reported the rumored arrival of three HTC tablets in the first half of 2011, and now a recent EU trademark filing could offer some insight into the software that may run on these mythical devices.

The filing for "HTC Sensation" is dated Jan. 19 and comes with list of associated goods and services as long as your arm, including "smartphones," "portable wireless devices" and "user interface software."

While a trademark filing is far from proof that a new product or piece of software exists, the HTC Sensation name is interesting because of its similarity to HTC Sense, the UI layer found on most HTC-built Android phones. If HTC were developing a custom UI layer for its Android tablets, then HTC Sensation would at least sound like a plausible name.

Right now, rumors like this are all anyone has to offer when it comes to HTC's tablet plans. However, it's possible the manufacturer may reveal more at next month's Mobile World Congress, so stay tuned. [via AndroidOS.in]
