Verizon Wireless is set to release four new Android phones at an unspecified date this year. One handset comes from Motorola, another one from LG, and the remaining two from HTC.

A leaked partial screenshot of what was allegedly a Minimum Advertised Price (MAP) list for Verizon was retrieved by Droid Life this week. The document specified an effectivity date of August 1, and showed the model numbers of the handsets covered by the MAP.

The effectivity date seems to be a hint that the listed devices’s launch or release dates are very near, probably in just a few weeks.

The first device on the list is the Motorola MOTXT875, which we presume to be the long-awaited Motorola DROID Bionic. Since the Motorola CEO himself recently announced that the DROID Bionic will arrive in stores in September, we have reason to believe that the other devices on the Verizon MAP list will also be released somewhere around that time.

Two HTC devices are on the list, one with model number ADR6425LVW and the other with model number ADR6330VW. The first one is rumored to be the HTC Vigor, which recently resurfaced on the NenaMark1 benchmark database showing the device as having a 1.5-GHz Qualcomm processor, Android 2.3.4 Gingerbread, and display resolution of 1280×720.

The other HTC device, ADR6330VW, is a mysterious one whose specifics are rather unknown. If the model number indicates anything, the device could probably be a variant coming from the HTC Incredible line. Some speculate that it’s possibly the silver and white edition that has recently been talked about. Other guesses include the rumor of a global smartphone with a physical keyboard just like the Merge. Bottom line is that we know very little about this curious HTC device.

The last item on the list is the LG VS920, whose model number is very close to that of the LG Revolution (LG VS910). Rumors say this could be the LG Revolution’s updated predecessor said to carry 4G LTE powers.

The truth is that we currently do not know much about these devices–not even about the DROID Bionic whose “official” specs seemed to have gone peek-a-boo on the Motorola Developer Network site.

As usual, we’ll give you updates as soon as they come. So, stay tuned.
