HTC just filed for trademark status on the term “ HTC Scribe”. And that’s just about all the information we have on HTC’s entry into the tablet game. In the trademark, under “Goods and Services”, HTC says it is a “Handheld wireless device, namely, a tablet computer”.
That’s about the closest we can come to any sort of confirmation on a tablet device. If you want to see the trademark application for yourself, head over to the USPTO.gov.
