This is My Next/The Verge has the scoop on the Motorola Atrix 2, and it looks to be slightly better than the first version. According to the site, the Atrix 2 will have a 4.3-inch qHD display, an 8-megapixel auto focus camera with an LED flash, 1GB of RAM, and 8GB of onboard storage, plus a 2GB microSD card (though it can accommodate up to 32GB cards). There is no mention of LTE support, however.
Like the original Atrix, the Atrix 2 will have Webtop support with accessories that include an HD Station and a laptop dock. The Lapdock is being identified as Lapdock 100, which looks to have a slightly different design than previous iterations. We're not too sure of what the exact differences are, but it does appear to be slightly smaller at 10.1 inches instead of the 11.6 inches on the original.
Strangely, it appears that you connect the phone to the Lapdock via the handset's upper edge. Motorola is presumed to be using the same docking technique with the Droid Razr, and we hope this will make the Webtop accessories more universal. Current Webtop accessories are unique to each phone model (the Atrix Lapdock won't work with the Droid Bionic, and vice versa), which never made much sense to us.
