diamond productions

(I am French, forgive my approximate English). I discovered Diamond Caves 2 in my middle school he maintaining four years there (I so freed everything the free levelgroups). I then played Diamond Caves 3, of whom I also have finishes the free version, and I plan to buy the complete version for Christmas.
I am a big fan of your games (also Maniac Ball) and I wait since quite a lot of time for a 4th possible Diamond Caves... I just post to ask you if he will exist one day?

In the pleasure to have an answer
