It's not like they'd make BW2 though, since ORAS their remakes have lacked any enhanced features, so a BW remake in this case would more than likely be Black and White 1
HG/SS will always remain the absolute top bar for any of their remake attempts, (including Legends tbh) but they've even stated quite a few times those games were packed with content and when you couple that with Masuda's answer about why the Battle Frontier/Level Difficulty wasn't in ORAS (and to an extent, XY) it's because GF believe that the attention spans of kids these days isn't the same as it was, so content like that wouldn't be appreciated (Which is a huge statement to make, that is probably incorrect)
So to expect that a potential remake would be Black and White 2, or would include features such as the PWT, would just be a let down. Of course their opinions could change over the last decade, as they've now seen their audience is far more than children. But given how BDSP turned out, with absolutely no Platinum features besides a few hints here and there, there's no reason to think that BW2 will be remade.
They could go for a curveball and create some form of Pokémon Legends x Black and White 3 hybrid but I doubt it.
Best bet for experiencing BW2 is to wait for the eventual Switch Online.
