I agree with @truck451 wish for a diesel; in fact, the entire lineup (Suburban/Tahoe and SIlverado 1,500) should offer a diesel… like the 4.5 Duramax that’s unfortunately been shelved:

As for two-door SUVs, the only possibility of that happening is with the new TrailBlazer… which itself may not even be coming to the States, even though I don’t think it’s a bad idea to make it available in North America:

But if it’s such a big deal to even bring the new Blazer here, a two-door variant ain’t gonna happen… and neither are the old-school body-on-frame Caprices (even though I appreciate late-model Caprice Wagons). The only thing that will be body-on-frame nowadays are trucks and full-sized SUVs, and even the latter are being replaced by unibody vehicles (Traverse).
