I sort of assume that this is all in hand by TPTB, but it would be nice to have confirmation.
Migrations to and from beta sites are discouraged anyway; migrations of on-topic questions to other sites where they might be on-topic are even less popular.
And as bwarner notes, doing so could unbalance a site that's already a bit... iffy.
I think we should first make sure that the Poker site can stand on its own. Shotgunning a bunch of already answered questions over there isn't going to do them any favors, and will cause confusion if the site doesn't survive. Once it looks to be in a stable place, it would probably make sense to migrate questions to that site.
As a corollary, it is my understanding that poker questions are still on-topic here, though it would certainly be encouraged to ask them at the Poker site instead.
