Treo 700wx to get Windows Mobile 6.0 upgrade?

According to some slides unearthed over at TreoCentral, it looks like the Verizon Treo 700wx could be an unlikely candidate due for the Windows Mobile 6.0 (not 6.1) treatment. Usually carriers like Verizon won't bother upgrading devices as old as these with newer versions of their mobile OS -- partly to induce future handset purchases -- so we'll have to remain a touch skeptical until such time as the upgrade really does launch.
