Hoenn Confirmed?

Well with the release of a few new Black and White 2 images, including the map, the internet has started talking and they believe there is going to be a Hoenn in the new games.

First, lets have a look at the map differences revealed so far.

So far, apart from the bottom left, it doesn't look like there are any major changes to the map, of course, most of the map has been covered in ice to hide the new things Nintendo doesn't want you to see, much the same way they used clouds on other maps to hide areas.

One of the speculations is about the ice itself, it seems to cover the edges of the map. Some people are saying that the ice is covering some of the transition areas between this region and the next.

So far there has been the release that the regional dex will have 300 pokemon, the most of any regional dex to date. I think this helps the speculation. I think that 300 pokemon in one region does sound a little compressed and one way they could spread out the species would be to expand the playable area, ie. Hoenn.

One thing to remember in this is that the gen 3 games (R/S/E) occurred in the same timeline as the gen 1 games, then several years later we have gen 2 and gen 4 occurring side by side and then finally we have the first two gen 5 games several years after that. The new games are set to take place a few years after the prequels, therefore, there is a massive time gap since we last saw Hoenn. Can you imagine going back after all this time, the changes that would have happened would be massive.

Remember that airport in Mistralton City?
That single airport?
It looks like that is a new airport on the mountain at the right of the new map. But why else is it there? Why do we need a plane to where we can fly to? Speculation says it will take us to Hoenn (much like the magnet train took us between Kanto and Johto.), which by now may have an airport of it's own. Although, I'm thinking it's more likely that this will take us to the battle frontier or some small island rather than a region.

A direct quote from Black and white after you find all the Seven Sages for Looker: "On a topic I must speak to you. Having received such a report, of someone far from here, who has seen a person like N and...a dragon Pokémon. I am on my way to verify the veracity of this information. We will meet again one day!"It appears that N has traveled to a different region with the legendary he has captured, could he have traveled to Hoenn?
