While fans have to wait a bit longer before the release of the next-gen creatures in "Pokémon Sun and Moon," Nintendo has already leaked some choice details about the upcoming game.

According to Nintendo Insider, it is confirmed that the November release of the new franchise additions will come with pre-order bonuses. Reportedly, Nintendo UK has already revealed that fans who will pre-order the new games' "Pokémon Solgaleo and Lunala Limited Edition" for the Nintendo 3DS XL will receive a free power adapter and a hard pouch featuring "Pokémon Sun and Moon." The "Limited Edition" version can be pre-ordered as a stand-alone purchase or bundled with the game.

Meanwhile, although the games are set for release later this year, Nintendo and developer Game Freak has yet to come out with more details on "Pokémon Sun and Moon." However, there are already early leaks on the games, such as Nintendo teasing that there will be more new Pokémon that will debut in the game. Observers predict that there may be more than 10 new additions, since most have already been leaked. This means that there will be additions to the 722 creatures already established in the Pokedex.

One of the expected tweaks for the upcoming games is Burst Evolution. Allegedly, Nintendo has already hinted that this feature may be present in "Pokémon Sun and Moon," since a previous report out of Japan teased that one of the Pokémon in the upcoming games has a "hidden secret."

Like other transformations in the franchise, Burst Evolutions also has a number of requirements to achieve. There are special in-game items called Burst Hearts which may be used to start the evolution. In addition, Burst Evolutions also require a higher level of bond between the trainer and the Pokémon, since this type of evolution allows a trainer to fuse with the creature. It is unclear on whether this new evolution is a sub-category of Mega Evolution, or a different type of process altogether.

"Pokémon Sun and Moon" will launch for the Nintendo 3DS on Nov. 18 in North America, Australia, and New Zealand, and on Nov. 23 in Europe.
