We haven't heard much about these since Verizon first showed them off way back at CES, but Phone Arena is reporting that a launch of Samsung and Novatel's new LTE mobile hotspots is now finally "imminent." That includes Novatel's USB551L LTE dongle in addition to the 4510L MiFi, both of which will be Mac-compatible out of the box (unlike Verizon's first pair of LTE modems), although that functionality has yet to be confirmed for Samsung's SCH-L11 hotspot. Still no word on pricing for any of them either, but Phone Arena says all three will be receiving a $50 rebate, so a price in line with Verizon's current, similarly-discounted $99 modems seems likely.
