If yesterday’s news that the Treo Pro’s launch date had slipped from February 15th to “TBD”, this latest bit of hearsay probably won’t help: “TBD” apparently means a full month later, with Sprint now hoping to get the Treo Pro onto the shelves by March 15th. Worse yet, that’s not even set in stone – it’s just Sprint’s hopeful launch target.

That’s the latest update to come from BGR’s whisperers, at least – and they brought some more details, too:

• LG Rumor 2: To be available in black and blue, also launching around mid-March
• LG LX370: Mid-range slider phone dropping in April/May – nothing too exciting here.
• Samsung Instinct Mini: Smaller, slimmer, EVDO Rev-0 version of the Instinct for folks who don’t need the full package. Sprint and Samsung dropped a pretty chunk of change into marketing the Instinct, so it’s no surprise they’re looking to expand the family.
• HTC Cedar: It’s the QWERTY candybar we saw back in January! (We’ve lugged the picture over for your convenience, check it out after the jump.) Look for it to drop around June.
