'Supergirl' Gets Closer to CW Move as Season 2 Deadline Nears

Per Deadline (the outlet, not the concept), CBS has reportedly intensified conversations to move Supergirl Season 2 to The CW, following initial talks that production might move from Los Angeles to Vancouver to save costs.

Should Supergirl move to The CW, might we expect any cast changes or serious budget crunches to alter the show?

Whether on The CW or not, a move to Vancouver would at least place Supergirl in easier crossover range with Arrow and The Flash.
