No, don't panic. It's just the names. According to
Brighthand the brand names Tungsten and Zire have been retired. The standard pdas are just "Palm." The Treo and LifeDrive lines will continue at least for now.
Kinda ruined my clever editorial... I was going to suggest that maybe the name T|X means the end of the Tungsten line. In a way I guess I was right. But you can count on Brighthand to dig into the story and give a nice account of the facts. Personally, I think it's really nice to have such a great variety of mobile device sites. From the grand daddy and ultimate in Palm news sources at Palm Addicts, to the consistently informative PDA24/7, to the very professional Brighthand and others. If you love to hear the news like I do, it's great to get such a nice variety!
