Nothing's guaranteed; with that logic then we must have 100% Final Form Freezer to go along with SWA Goku too
The only bit of logic that I see Tamashii Nations doing is that they like to "pair-up" releases. Either a duo who goes together, or two characters who are supposed to fight one another. This is something relatively new but they've done it with a few of their lines now:
Injustice Batman vs. Injustice Evil Superman.
Naruto vs. Sasuke
They've done it with the Stars Wars line: Darth Vader and Jedi Luke, Padawan Obi-Wan and Darth Maul, and now Mace Windu and Jango Fett.
With Dragon Ball: Android Trio, then we were supposed to have Ultimate Gohan and Vegetto vs. [Super Buus], SSGSS Goku vs. Golden Frieza, Beerus and Whis, and SSGSS Vegeta to round out Dragon Ball Super.
They haven't started a pattern with the Regular releases, but if it follows a similar train of thought (logic? Hmmm), then the Vegeta being released will indeed be Cell Saga Vegeta, essentially Super Saiyan Vegeta 2.0 because he "pairs" with Armored Trunks.
