It's just conjecture at this point. Either way it goes it's still a really bad choice. The base game has just 158 Pokemon, if they introduce packs for new Pokemon or not shouldn't matter. It's disappointing anyway, lol.
Oh yeah. I agree. If anything I wish they had gone with the Rusty's Real Deal Baseball or Sub Wars model for this instead of Candy Crush. There's a reason why that app got deleted off my phone within a few hours...
