It’s not quite the February 15th rumor from a couple weeks ago, but BGR is reporting that the Palm Pre might be launching around March 15th according to an end-of-life (EOL) list of Sprint handsets leaked from somewhere inside the company.

The February 15th phone appears to be the Treo Pro, which will replace the Palm 800w. The Palm Pre has a “target in-stock” date of 3/15 and will replace the Palm 755p if the leaked document is to be believed.

Unfortunately, the actual document hasn’t been posted anywhere so, as always, take info like this with a grain of salt. The list below shows end-of-life dates for current devices, with each device followed by the device that’ll replace it (if applicable).
