I don't think anyone ever thought of expansion. The talent pool is too depleted as it is.
It's about entering into strong markets that would be financially viable (unlike about the 10-12 that exist right now). Off the top of my head I could see Charlotte, Memphis, Milwaukee, Atlanta, Indianapolis and New Orleans all at risk of losing their teams.
So yeah, expansion, no, but once Seattle gets a team, if there's a strong ownership group, Vancouver would get one (heck, maybe even the Grizzlies).
