I have actually seen the promotional pictures ... and I think I need to stop, because they seem a lot more spoiler-y with Continuum than they did with AoT. It's all context, though, I guess. I have been trying generally to avoid other spoilers. It's difficult.

You are right about the actors, because even the little scene of Jack & Sam in The Shroud was terrific. And fortunately, I watch the show for way more than ship, so .... *shrugs*. Either way. I really liked AoT even without Jack and Hammond. It was nice to see the team back!! And Continuum looks like a ton more old-school SG fun. With OMG the entire Goa'uld fleet - did I mention that my mind, it boggles?
