Waiting for Clio V? (it only looks like a facelift for me)

I am in possession of a Renault Megane Coupe BJ 98 and have a pickerl until September (after that it is due). There is also a repair of two wheel bearings. I have now thought to get a half-priced day registration of a Clio IV. Now the following questions are asked: 1. Should I wait for the Clio V, since the interior should become more casual? 2. Does this ever come to September? The published sales starts vary yes. 3. The price would be true Probably not so attractive by far, do you? 4. Do you think that the vehicle will still have many childhood diseases?
