The analyst I know spoke with Palm management this week and shared with me that Palm expects to release a new "antenna-less" Treo in July on Vodaphone's network. This matches the description we'd previously been given of the Treo product codenamed "Hollywood." This is expected to run Windows Mobile and (my best guess) will have a 3G (HSDPA) radio. My informant says it will be released with a big media fanfare in five markets.
PalmInfocenter has leaked pictures of what might be the Treo in question.
Palm is on track for the announced four 2006 Treo releases, but it sounds like Treo #4, previously thought to be a lower cost Treo codenamed "Low Rider" may be something different now. My confidential source said that his contact at Palm spoke of a Treo that (in my interpretation) matched the description we had for Low Rider, but said it would be released in 2007.
