So, I noticed that Kings Dominion's Water Works will be renamed Soak City next year on facebook. They will not only be getting that complex, but also revamping the path and entrance from inside the park itself. This means Cedar Fair is apparently still interested in making Soak City a brand across the parts of the chain that don't feature it.
I have a new theory about what the park might have in store for 2016 now:- A slide complex (or possibly more) on the other side of Thunder Road, with a new changing facility, bathrooms, and food options over there as well. (and maybe even an alternate in-park entrance through
- Upgrades to the current changing facilities, bathrooms, and food options (it's not looking so great in some areas -and the bathrooms/changing areas were unbearably humid as of my last visit to BB).
- Possible rename to Soak City with the current Aussie theme being removed by way of repainting and re-themeing the current attractions (i.e. new ride names, new signs, etc.).
- New signage to greet visitors as the enter the water park from the gates (possibly for Soak City or just Boomerang Bay).
- Rumored Thunder Road-related improvements for the 40th Anniversary. (maybe a new sign, new trains, improved queue, or something else along those lines).
- A possible Carowinds Plaza revamp with a fountain, gold sign being repositioned, and a wider space beyond the bridge (as they have hinted).
Any of these seem possible to me, but they are also equally as unlikely.
The only thing I know for certain... I hope I will enjoy whatever is announced for 2016!

BTW...
I like the fact that Carowinds has public said they pride themselves on providing a "first job" experience to the youth in the Charlotte metropolitan area. I know you didn't say otherwise, I would just like to point out that I find it very commendable.
As far as anyone's suggestion that Carowinds is going downhill by making much needed changes, well, that's just a benighted notion.
