As many people have correctly pointed out, the crew were lucky to have TD renewed. They're likely to stick to something familiar and safe, so I don't think we'd receive a new cast. I think we're going to see 2/3 1st gen, with a few 2nd gen and 3rd gen who need redemption or could use some more development. This way they're pleasing most fans who favor the original cast, but theyre also giving us a little taste of ROTI and PI contestants so it doesn't get stale with pre-occupied relationships and rivalries that already exist.
