Mega Beedrill looks delicious.
I wonder, if we get Gen V Legendary Megas at some point what will they look like? Will they put a bit of Reshiram in Zekrom and vice versa, or go in a different direction? Also I think it'd be a safe bet to say Mega Kyurem would have the appearance of the Original Dragon. Stat wise it would even work out since it would be 60 points higher than Black or White Kyurem.
Holy shit, I just realized that when we get to Black and White remakes the games will look amazing, but what will they do about B2&W2?
WHY AM I ASKING SO MANY QUESTIONS?
I imagine they'll take the energy motif even further (not unlike Mega Kyogre and Mega Groudon with their Tron Lines) though the Yin-Yang mixing is also a likely course. (Perhaps even combined).
Mega Kyurem is almost certainly going to be the complete Dragon (unless they go ahead with another form change, though I doubt that since giving something an offensively-geared 760 BST with the ability to use held items would be rather horrific). That was the last major hanging thread from the Unova games and I can't imagine them neglecting that in the remake.
I think they might end up either neglecting the sequels or combining them into the BW1 (Black Blaze and White Bolt?) remakes as a post-story (because for-serious BW mostly had awful post-game quests that merit replacing)
And the future is never certain, so there's never a problem with speculation.
