My thoughts on the center land
Well, there is another dessert in the game. (If you count the ruins in R/S/E). I really hope this doesn't turn out like the blizzard in D/P. That was just horrible!
The Hinun(?) City looks as big as it was made out to be. I mean when looking at other screens of other maps, and this map itself. I think that this will be the largest city in the game! I'm pretty sure that this will be a city that you come across several times in the game, and will have a lot of activity. It will probably hold the contests, the game corner, the super PC with the GTS, The Battle Frontier, A Gym, The enemy's base, and a radio tower. These things here would fill up the city, and make it as big as it can get. I also think that the market will appear here too!
Above the dessert seems to be a park of some sort with rides and stuff. I would not be surprised if they used this as a town. It would probley be photo-gentic with all the stuff, and there would be a lot to do. This is also the best place to have a dark gym! Clowns everywhere inside the gym, and the Gym leader is a clown/circus master.
Above this you see a pool of water with an island with a shrine in it. This is one of the places where I give speculation for the legendary apperenced. Maybe not the two cover ones, but the ones that are just in-game. Maybe it'll be the place where you get the 3rd..
North of that there is a town, simple enough. Then there is what seems like a giant marsh. Next to it is a bridge, and a small mountain. I have high suspesion that this will hold the ever so famous Pokemon league. The placement of the league is a bit random compared to where the other leagues where.
Right Side
There isn't much shown here for me to tell.
There seems to be a white mountain behind the text, but I can't say for sure. This could be where the electric cave is! I'm guessing that the player would go through here to get to a town that would be where victory road really starts at.
On the southern side, I see a large forest. I'm guessing this is where that one forest was!
The starter town looks like it can be the one is the lower right, while the secondary town is just to the up-left. Then theres a town in the mid-right which I think will hold the 1st gym. Then, you would either go north through the cave/cross the bridge, to the castle, and over to the city!
Theres a lot of trees.
Left Side.
The town that is connecting with the red drawbridge must be the other port of the world. This town also holds a light house, and will probably resemble other port like city's from the past. (cough olivine cough)
I see a dark red evil cave, some ruins, and maybe a town in the north of the left side, however I can't really make it out what to be.
The big thing I see is all the mountains in the back, which can hold a legendary, go along with the story, be tunnels, or just being there for no real reason.
Thats my thoughts on what I can see/uncovered
Oh yeah: The honny comb place looks like a gym. It could hint off a Bug Gym!
