What is the Next step in Thing Thing?

One must wonder. Will there be a new Thing Thing added to the powerhouse series? Thing Thing Arena 3, is a classic yet it is old. Hey...who knows? Will there be a other Thing Thing. Give me a short beginning of the game, and a ending. Well....if you don't know what TT is, play it! It is fun!!! (Just a game.) Well that is it. Thanks to all who answer.|||Well i haven't played the 4th installment but i think he will fund a purpose in life or get revenge on the people that created him but it is a good game though =D
