The Treo 850 is indeed with a codename Skywriter, it looks similar to Palm Centro, but the source says it is a evolution from Treo 750 series.
The Treo 850 will be running the windows mobile 6.1 professional. Similar to the upcoming Treo 800w, it will come with built in WiFi and will be using a micro-USB connector for battery charging and desktop sync.
