Yes I saw this in Orchid room in RWS. I went to do a search online and found that there are 2 new versions of Cash Cove. One is this one which is basically playing 4 screens at a time (so if you spin $2, each screen is based on 50c bet). When you get 3 of the bonus symbol, the screen will play the free game but if you get one or more of the gold bonus symbol, free game will play on all 4 screens. This version is called Cash Cove Monster Catch.
There is another new version called Cash Cove deluxe but I cannot find any additional info on it.
This type of new version sounds like copying Aristocrat. Monster Catch is like Wonder 4 version where you have the 4 screens at one time with super free games if you kena special bonus symbol. Deluxe version my guess is maybe is based on 1024 ways vs 243 ways now?
