Having one device leaked is so last fiscal year, man. Verizon is hip to the new trend of leaking out details of all of your devices and giving people a heads-up to not buy phones that are out right now since they're just gonna get replaced anyway.
Androids aren't the only things on show, but forgive us for omitting those not relevant to the droid-heads (check BerryPolice.com, great site).
Motorola's got the lion's share of the devices. Starting with the Venus, a portrait QWERTY phone to be released this month that Engadget thinks may be similar to the Charm. It isn't mentioned whether or not the phone is a slider, but we do know that there is one out there somewhere.
