Pretty sure the video games are still considered canon on the level of the books and comics, at least for now. And you're forgetting games like TFU. Battlefront, as far as I'm aware, is considered canon, not sure about Demolition and Galactic Battlegrounds.
This I agree to. Star Wars will be the same; no matter how much hate the fans will have toward the new movies, they'll watch them.
Battlefront just takes battles that we know happend and allows you to play in them. Allthough if one side wins a battle thats not canon.
TFU is a weird one. They say it's canon supposedly G-canon but it in no way fits into the actual canon. It doesn't even fit into C-canon. I mean you talk to Yoda on Degobah so how did this not come up when he talked to Luke?
"Oh hey watch out there is another Jedi who can pull entire Star Destroyers out of space. "
