We have heard a bit about the Galaxy Tab 3 8.0, but now proof was obtailed by SamMobile. SamMobile had discovered that Samsung is going to change some of its lettering for model numbers in the coming months.  After some research, it  appears that the new numbers are already appearing on at least one page in Samsung's Internet ecosystem, but the pages they have not yet been published.

Here's an example.

Galaxy Tab 3 (8.0) 16GB 3G (SM-T3100****** - White) Week 27 (Week of July 1)

Galaxy Tab 3 (8.0) 16GB Wi-Fi (SM-T3110****** - White) Week 24 (Week of June 10)

We have no idea what the prices will be for these devices yet, but we will keep you posted.
