Serebii posted last night that there is a name attached to the image, Soritiba. It was trademarked last year by GF. I did a Google Translate, chopping up the name and this is what I got...
"Sori = A Sled tii = Royalty ba" = Horse
"So = Software ri = Re tii = Royalty ba" = Horse
"So = Software ritii = Security ba" = Horse
Now, it could be any of those, or it could be none of those. But, what you must remember is that the last character (Ba) is the Kanji for "horse". Could we see an Epona-esque Pokémon? A Digimon x Porygon-like Pokémon? Or is it something else entirely?
