We’ve known for a few months that Palm had another Windows Mobile Treo in the works; today, we know a good bit more than that.  Images and information regarding the upcoming Treo Pro briefly appeared on the Palm.com web site.  The content was pulled shortly thereafter, but not before some eager Treo fans were able to grab some slides from a presentation and run.

The Treo Pro will be, at least in one incarnation, a GSM handset with HSDPA/UMTS compatibility.  Other features include Wi-Fi, GPS and microSD expansion.  No word yet on price or availability.
