How far away is that? It might be completely different universe.
Probably far enough that the game will have no continuity with previous generations, no known timeline, no references.
Also, the region seems not to be based on any Japanese region, the town looks awfully lot like New York. A non-Japanese region? Sorry, Pokemon is supposed to be Japanese. American "Pokemon" ought not to exist.
From the information that we know, there is NOTHING in these games that would relate to the Pokemon canon.
There's a slight chance that next CoroCoro or final game will prove me wrong. But for now, nothing points to that.
Considering BW as the same canon to the Pokemon Series is a really, really far fetched. We shouldn't be so liberal in the definition of canon.
