One thing I stoked about is that if the 'interrim' films visit other areas of the Star Wars Universe we will get some of those figures originally seen in the cartoons. I'm having a pile of Pyke when they come out for sure.
My hope is that during the gap between the Solo line and Episode 9, we might see a return to a saga legends type assortment with characters spanning the entire SW universe. While I doubt we'll see anything from CW or Rebels repacked in their animated form, we might see some realistic versions of those characters. I'm happy a Pyke appeared in Solo, because they surely will never give us a CW version. The only big question is whether there will be a line for the animated series, Resistance, because that may dispense with the probability of a legends line.
