Circled some interesting items worth discussing.
EDIT: You should look at the picture while you read this.
EDIT_2: And as for the Japanese Text, all I can make of it is that one of the words translate to 'Specialist'. Could be wrong though, my Japanese isnt that good.
Red Circle- Not much to discuss, it seems like an early version of the Black/White Map, or a newer version of the map to be featured in Gray (I will use the title 'Gray' because it is the most likely title)
Blue Circle- I'm not so sure what this would be, It seems like an Ice Cave, possibly where Kyurem would be located in Gray. Seems like a healthy discussion. It also appears to maybe be the remnants of Kyurem's meteorite. Could be used in Kyurem's sidequest.
Yellow Circle- It appears to be an early version of the animation when High Link is active, or a new version to be used in Gray. My question: Why is it green? Maybe hinting an Emerald remake? Sorry getting off topic.
Orange Circle- Appears to be a different animation of N's Castle attaching itself to the Pokemon League.
Black Circle- A new night animation? Im not sure about this one. It looks like something is flying in the sky though. Possibly Kyurem?
Purple Circle- Unsure of this one, it was previously hinted to be a new pokemon. Maybe a new form? Seems like a healthy discussion.
Silver Circle- Now what could this possibly be? I zoomed into this picture's area, and it appeared to be an underwater city that was resurfaced. Maybe something achieved in the Underwater Ruins found through Dive? Maybe this could be the area where we could find the 'God Stone' rumored to change Kyurem's form? (If ever he had another one. Seems plausible.)
Green Circle- This could be an early version on The Hiun City Pokemon Center, Or a newer version of the Hiun City Pokemon Ceter to be featured in Gray.
Now these are only theories, but they seem interesting to me. Then again I could be wrong, and this could all be a board featuring all the prototypes and early drafts of Black/White.
