Wow! 2015 is a very aggressive goal for such a massive project. Looks great from the model and video though so I will definitely be following the news on this.
As for all the Vekomas, it makes sense to me because I would guess they tend to be on the less expensive side of things and it also helps that the park is making mostly smaller "family-friendly" coasters.
I also think it's great that they will have a couple areas open year-round, even a coaster in one of those sections.
And of course, let us not forget blessing the land with vodka...that is surely a recipe for success :-D
