I would put a priority on EP 9 toons if you want to stay on the meta watch. FO/Res. and apparently Palp. Then be ready for whatever new cash grab they throw at us to unlock the next meta which you would be prepared for if you focused in EP 9. R2 could be in the mix. I'm working on R2 right now. C3P0 is at G11. BB8 G11. I'm sure they will all play some part even if minor. In the inevitable event that they release jedi luke + x-wing I'm sure R2 will be needed. I think he is a worthy long term investment as most main movie line toons are.
