Yes, I was disappointed that after seeing the prototype for Baze show up and got photographed at so many shows, he was a no-show for PO.
I got Churrit - it's a great figure but he looks incomplete on display w/o his buddy Baze. I hope HT reconsiders and puts it up for PO but I think pigs will fly first...
As for Lando, yes-the only three ESB-related figures I hope are must-do's for HT are BDW Lando, Bespin Han and General Veers.
As for "Solo", I am very interested to see what turns up on display at SDCC- will there be any more entries from this? Qi'ra (Kessel outfit please), Lando, L3, Range Trooper, Beckett and Enfys Nest would all make good figures but- as we've seen with TLJ and Rogue One, what we might consider "essential" or main characters get ;left in the lurch.
Krennic or Cassian, anyone? Poe or Hux?
We might see an new Chewie (he's teased in the proto-photos of Han), and Mimban Trooper (muddy stormie w/ black cape). And MAYBE a Range Trooper, since so many other versions are out there giving him high viability from this movie even if the screen time was light.
We may see protos of Lando, Becket and (hope against hope) Enfys Nest* -but like many before them, they'll never make it to PO status.
* - I really want a high-end figure of this character- the awesome design elements and intricate detailing could potentially be a real show stopper on the shelve-but I know I'm dreaming...plus, all of that gear and detailing could make it an expensive figure.
