So, who do we know definitely has some kind of new form, even if it may not be a real 'Forme'? The answer: Notch-eared Pichu - a baby pokemon introduced in G/S. And, if I recall correctly, wasn't there an Odd Egg that could hatch into one of the newly-introduced babies in G/S? Maybe the Odd Egg is truly 'odd' and hatches into a slightly altered form of one of the babies, a possibility of course being Pichu in its 'Notch-Eared Forme.
That would make sense. Though I've been wondering, is the "notch-eared" pichu even confirmed as a new form yet or are people just thinking so based on the picture?
Wasnt regigigas suppose to get a new form? Mayeb it'll get one for this game.
