Since their release, there has been a lot of discussion related to how they will affect gameplay. Many people are worried that they will increase the power creep we've seen over the generations (for example there are more high stat Pokémon in gen 5 than in gen 1). From here on out, I will be expressing my opinion.
These new Mega evolutions bother me a little, but less with their stats or anything competitive. I just don't like the "Mega" prefix. It makes me think a little about how digimon name their creatures, however I do realize that many Japanese games/anime use prefixes for powered up modes. I don't think it pulls away from creativity, but I do wish they had chosen a different prefix. Now, it is possible that they aren't actually "named" Mega in play. For example, making Giratina change to Origin Forme Giratina doesn't change it's name. It's still just Giratina. The community just knows it's Origin Forme Giratina.
On a more competitive stance, I'm not going to say that the Megas won't be incredibly overpowered. There's no way to know. However, hopefully stats won't increase too dramatically. Maybe they will just shuffle stats around. I do see potential here though. As there has been the power creep slowly making the standard of competitive play higher, Megas could bring older Pokémon into the competitive play environment. For example, Kangaskhan is good, but it is commonly passed over for stronger Pokémon. Now with it's Mega evolution, it gets a new ability, Parental Bond, that allows it to attack twice. This could truly be a great way to get old favorites like Charizard, Aerodactyl, Parasect, etc back into the game with new stat allotments, new or different abilities, and changes to typing.
Now like I said, the Megas may be too overpowered, like some legendaries. The good thing is Megas require a Mega Stone item. That means there is a trade off. You'll never face a Choice Scarf Mega Mewtwo for example. Additionally, if they are too OP, tournament organizers can ban the Mega Stones for that tournament. Also, Nintendo has already said you can only have one Mega in a battle at a time, so no double or triple battle Mega spamming.
Personally, at the moment, I don't see that many negatives to this new play mechanic. It's just a matter of how they are implemented. I look forward to seeing what other Pokémon get Mega evolutions.
