Before its highly anticipated release in November, a new Pokemon Omega Ruby and Alpha Sapphire gameplay trailer has surfaced on YouTube.

In this new Japanese trailer, we see a lot of Pokemon cycling in Omega Ruby and Alpha Sapphire. We also see an awesome evolution of Pichu to Pikachu.

"That evolution scene was amazing!" commented Aussie Riolu on YouTube.

"I like this evolution sequence better than any of them in the past," wrote defensivebastiodon on PokeJungle.

"I don't know if anyone noticed, yet it seems like GameFreak is returning to Black 2/White 2 style of Gyms, where the Gyms blend in with the surroundings," added Afarr.

"I think this also confirms Winona is back," added Dicie regarding this Pokemon Omega Ruby and Alpha Sapphire gameplay trailer. "Now all that's left is Wallace/Juan. Tate and Liza's Gym was briefly shown in a previous trailer. If they haven't revealed anything connected to them by now, something major must've changed."

Most recently, two new Mega Evolutions were revealed with Mega Slowbro and Mega Audino.

Reportedly, Mega Slowbro remains a Water/Psychic dual-type, but gains the Shell Armor ability. It will also have boosted Defense and Special Attack.

Meanwhile, Mega Audino will be a Normal/Fairy dual-type with the Healer ability, and will have increased Defense and Special Defense.
