Is anyone else unable to connect to Nintendo Wi-Fi on their game due to “Ongoing Maintenance”?

There's maintenance going on right now. I've seen some people talking about it on other sites.

Sorry about the double post but Serebii just put out an update this morning that the Movie 19 trailer was shown at an early showing of the Hoopa movie and Zygarde was in the trailer.

This pretty much assures that Gen 7 won't be here until 2017 and that Gen 6 will continue through 2016.

Well considering that there's another Mythical Pokémon yet to be revealed/obtained (Volcanion), it's worth waiting another couple years for Gen VII so we can get Volcanion first, so by the time Gen VII debuts, we have both Hoopa and Volcanion so we have a 100% complete Pokédex up to that point.

I really can't wait to get my hands on Volcanion

Would be cool if Volcanion get's incorporated into the story and isn’t just another Event Pokemon.

It would already be revealed if it wasn't an event Pokemon.

Neither can I. Not only does he look awesome, but his one-of-a-kind Type combination (Fire/Water) is also epic.

Can someone PLEASE get me a legit Hoopa ASAP 'cause I'm still getting trolled by those who either have hacked Shiny Hoopa or trying to BS me with the Hoopa Egg scam.

You can't. Until the event drops, you can't trade a Hoopa.
You had to have downloaded it into your game.
