(Having played every gen game except Fire Red, Pearl, B1, BW2)

Game code for Mega Lati@s already exists. Mega Latias is pretty much inferior to Soul Dew Latias. Mega Latios becomes an awkward mixed attacker, and sort of is a waste of the mega slot.

I do foresee Mega Metagross, perhaps Mega Altaria and Mega Flygon. At least using Gen 4 phys/special mechanics is definitely an improvement, as expected.

Secret bases are of course nice, if they do something like they did with Gen 5's Entralink (I actually used that stuff with my bro) even better, to a point.

Having a competitive difficulty would be great too.
