My guess would be Whistler. I think BC99 is part of the next update.

Looks like about 1200 km give or take.

Since so many people are asking about releases etc I decided to show this very high quality graphic Bricksathome made a few days ago: (red = 0% done (barebones), green = 100% finished, yellow 50%) As for a release, I seriously have no idea. I would love to see it this year, maybe even after the sum...
