A report has been made, that a leaked Sprint document shows Sprint will EOL the 800w in April. The Treo Pro being its replacement that will be released on 2/15.
The 755p will be EOLed by Sprint in late May and replaced by the Pre to release on 3/15.
Flavors of the Palm Centro will start going EOL in June and through July.
The Moto QC9 will EOL in mid June.
The HTC Touch Diamond will EOL in July.
(This one is interesting, since Verizon might carry the Touch Diamond soon. With Sprint having no Touch Diamond replacement listed, it would leave Verizon as the only CDMA spot with the Touch Diamond. But I guess Sprint feels it would have run its course with them by July.)
