The Taipei times quotes HTC's own financial executive Cheng Hui-ming at an investor's conference as saying they will launch "the most important product for HTC this year" at an event on May 6. Cheng wasn't too forthcoming with details, but it seems like it's going to be a "Touch" phone—as in one of the HTC Touch models—and be called the "Diamond". He says that it's going to be so good, he's "confident of landing orders from most major carriers," but warned about possible delays because they haven't gotten certification for the phone yet. Sounds very interesting. Could it be this phone? [Taipei Times via Engadget]
