Verizon is going to be getting the Galaxy Tab 7.7 in stock in just two days (March 1st). They will be selling it on a two year contract for $499.99. It sports a 1.4 GHz dual-core processor that I assume is Exynos like the Galaxy Tab 7.7 announced at IFA last year. It will launch with Honeycomb 3.2 and will likely be upgraded to Android 4.0 Ice Cream Sandwich eventually.
The Galaxy Note 10.1 was just announced at Mobile World Congress. It is a mix between the Galaxy Note and the Galaxy Tab 10.1. It borrows the S-Pen and 1.4 GHz Exynos processor from the Galaxy Note and the 10.1 inch display from the Galaxy Tab 10.1 with a 1280 by 800 resolution.
Not too long ago Samsung announced what they are calling the Galaxy Tab 2. The Galaxy Tab 2 was essentially the Galaxy Tab 7.0 Plus with phone functionality. Likewise, the Galaxy Tab 2 (10.1) is the basically the Galaxy Tab 10.1 with phone capabilities.
