I know I've brought this up before but it didn't get much attention: isn't ORAS an awful (or at least questionable) timing for releasing megas like Beedrill and Pidgeot? First, they are much more related to the Kanto games than other Kanto pokémon such as Slowbro. Not many people have ever used Slowpokes on their FRLG runs, but I doubt you'll find someone who haven't caught a Weedle or at least a Pidgey. Also, the Slowpoke family got a second evolution in Gen II and Regenerator in Gen V, which made them more mainstream and not the kind of thing you'd only see when playing FRLG or even HGSS in Pidgey's case.
But aside from the totally random timing, what upsets me the most is the fact that XY was the perfect opportunity for introducing them. The mega Kanto starters, Santalune Forest which is basically a copy of Viridian Forest where you can even find wild Pidgey and Weedle. There was a whole bit of nostalgia going on in XY and mega Pidgeot and mega Beedrill would've fit in perfectly. You would be able to mega evolve not only the starter Prof. Sycamore gave you, but also the Pidgey/Weedle caught at route 2/Santalune Forest, possibly the first pokémon you ever caught in Gen VI. With the new graphics. But no, they preferred to introduce them in ORAS instead, where they won't be catchable until post-game if at all.
I'm happy for the new megas and hope they breathe new life into those two forgotten pokémon, but I can't say I'm happy with the way they're being introduced. We're aboard the Hoenn hype train and then we find out Viridian forest is going mega. In Hoenn.
