They will prolly start to consolidate lines and keep the more popular selling cars, just rebrand them or use them as replacements for less popular models under the brands that they keep.
GMC sells the same trucks as chevy does, just different option packages, so they will all dissapear, although the heavy duty work trucks will prolly continue under the GMC brand, but only sold from chevy dealers. Saabs days are numbered, although i think that saturn might inherit a model or two between saab and pontiac.
