I actually really like Litten's final evolution based on the 3d model. Though, I still like the other two more. As a group I think they are the most solid. But yes! I was relieved to FINALLY have my mermaid sealion confirmed and in its 3D model.
As you probably know, the leaked list was fake...good thing I didn't reserve the name.
It still doesn't rule out the possibility of multiple starter formes...and we know officially now that the secret about Rockruff relates to evolution...thus it's the same for the starters.
I am still of the mindset that there is simply going to be a day and night formes, though whether or not these are PERMANENTLY based on when evolution occurs or INTERMITTENTLY CHANGE when it is night or day. Will make a huge difference. If Rockruff is a werewolf, it indicates that it will be intermittent.
I could can get on board so long as the other forme is not completely different - and maintains a beautiful sea lion appearance and doesn't grow giant biceps -- if that is the case, I hope these split evolutions are PERMENENT!
(Or I will just play the game at whatever time the siren is at play).
But, who knows, for all we know different versions might have different evolutions...so I am NOT preordering until November. (I would be devastated if someone I ended up with Ballio in my version XD)
I feel that the split evolutions with different typing is something very odd indeed, especially considering the starters and Rockruff are involved in it which likely hints that split evolutions that change types are the secret they are holding.
As to how I can accept this mechanic it will come down to what circumstances determine each particular typing because I know you want your Water/Fairy siren-sea lion beauty.
