The Black 2/White 2 number is for Japan alone, because it launched there months before it launched anywhere else. Ultra SuMo is pretty far behind, launches aligned.
Good! I think everyone was a bit disappointed that we didn't get a Moon 2. Especially for the fact that it felt like they were teasing it.
I have doubts that GameFreak will use the new technology they have at their fingertips in any above-average-ways. Here's hoping they aren't lazy about this 3DS to Switch jump.
I can see where you are coming from. Still an average look HD game is still a big jump from the 3DS games and their 240p screens. Honestly I am more worried about them rushing the game. If they started development on the Switch version in 2016 it will barely have two years of development time if it releases in 2018.
