Palm Treo 755p on the Horizon?

The Palm rumor mill is humming once again as leaked pictures of the purported Treo 755p have begun spreading on the Web. Unearthed by the sleuths at Engadget Mobile, the new EV-DO phone looks to be the latest in a line of Palm OS—or rather, Garnet OS—Treos, this time with an internal antenna replacing the annoying stub on the old 700p.

From what I can gather from the pictures, the 755p looks more or less like the GSM 680 Treo on AT&T/Cingular—and that includes, unfortunately, the 680's fairly substantial girth, as well as a version of the Garnet OS that looks virtually unchanged from last year's 700p. According to Engadget's tipsters, the 755p will arrive with a 1.3-megapixel camera (again, nothing new), while a Gizmodo informant has pictures of a maroon flavor of the phone, which also betrays a new IM app (a welcome addition, if it's true). Interesting, but so far, I'm not seeing any details that would make me rush out and replace my trusty 700p. Word is that the 755p could be launching on Sprint in the next few months.
