Sprint puts out fact sheet for dual-mode U301 WiMAX modem, release imminent?

So Sprint just published an official fact sheet for a U301 USB modem with support for both WiMAX and EV-DO -- it's not accompanied by any press release or product page on Sprint's online store, but we can only assume this means that a release is around the corner. Of course, the dual-mode capability alone doesn't set it apart -- the carrier's existing U300 model already handles those duties with aplomb -- but what seemingly sets the U301 apart is its support for Mac OS. We'd just as soon they'd release drivers for the U300, but failing that, alright, fine, we'll take a new modem. If we're sustaining over 3Mbps down, we'll take a lot of carrier and manufacturer abuse, actually.
