^That's possible, they've certainly been trying to branch out more with shows and festivals. Considering DW did that for 2009, maybe we're due for the same treatment.
On the other hand, The Giant Swing wasn't announced until October 18, and GE wasn't announced until November 6. I don't recall there being any construction noticeable before hand in either case, especially TGS.
Considering the Branson market, maybe they'll hold back again this year, but they have been investing a lot in every other park, and their competitors are gaining a foothold on the market. As far as rides are concerned, they'll need to put up or shut up soon. Instead though, they could do heavy emphasis on some other aspect of the park such as shows and festivals. Either would be great, but it seems like they'll have an easier time marketing a new ride, so that's the direction I see them taking.
Heck, now that I think about it, at this point I wouldn't completely rule out a new coaster for next year, as far-out as that seems. I'm sure there will be something worth looking forward to.
