>>7938465If we were to determine an release order, I'd think more like...
1. Jeice
2. Burter
3. Recoome
4. Guldo.
Why? Because of the promotional pics. They can't showcase Burter without Jeice next to him and Jeice can be showcased with Ginyu since he has enough scenes with him. Recoome is one of the most popular and the one we've seen the most in action. Guldo in last position because it's certainly the least popular and he would be the only one missing to complete the Tokusentai.
>>7940214When the Saint Cloth Myth collection (Saint Seiya) was at its golden age, Bandai had released the 5 minor bronze saints: Jabu, Geki, Ichi, Nachi and even Ban who had no dialogue in the manga. The Dragon Ball Figuarts lines doesn't seem to be doing badly so I think there is a high probability that they will release all the Ginyu Force members.
>>7940303I don't have any Buus, but I can confirm that Nappa is a lot of fun. You seem to have a limited amount of space (or a limited budget like me). So I advise you to choose the character according to the saga (Saiyans or Buu) you like the most.
