Aside from a possible release date and some rumors about the hardware, there's not much we can talk about the upcoming flagship tablet from Samsung. But according to a renown leakster, Evan Blass, the tablet lineup will skip the S5 name and will go straight to Tab S6. This is rather unexpected especially when you weigh in the fact that the budget variant Galaxy Tab S5e is already on the market. Sadly, @evleaks didn't go into details, so only time will tell why Samsung is skipping the Tab S5 name. Source
