Sprint pushing national QChat launch back to June 15?

Looks like we might all be waiting just a few more weeks before we're given the green light to descend into the next generation of push-to-talk nirvana (or hell, depending on your perspective). phoneArena is claiming that the national release of Sprint's QChat-powered PTT system -- and the phones to go along with it -- has been pushed back to June 15, though it's not known whether the delay's due to technical issues, a desire to have all of the new phones available on shelves at once, CEO Dan Hesse's whim, or something else entirely. For what it's worth, business customers in Denver and Kansas City already have access to the Sanyo PRO handsets, so you guys should really revel in your exclusivity while you still can.
