When you put lipstick on a pig, it is still a pig. The theming around the place will be a nice difference (like in Bugs land in DCA), but it still will not solve the capacity issues nor the fact these are still carni rides.
Yes, I will admit, I am a little happier now I have seen these shots, but the attractions themselves will still have monster waits, the will be horrible in the winter, and they can be experienced anywhere. What's the betting that if they are not installed in the begining, there will be barriers stopping people interacting with the props, like they did with Race Rally. Also, I have to laugh that I am probably one of the few DLP regulars that ever played with a slinky dog, lincoln logs, and tinker toys.
So in short, yes, I am midly surprised with the theming, but still mad this is the direction they have gone in. I am somewhat relieved John and WDI are making this happen, but Disney's batting average for attractions designed in this millenia is really poor.
