If they have to (or actually, I WISH), they can fire everybody and get both new people leading TDU3 as developing TDU3. I have no faith in the current team being capable of making a successor to let us forget TDU1 and TDU2, both good as bad things, and it will still be Atari in charge, no matter who the developing team will be.
Eden has proven themselves to have insufficient skills and experience on many aspects, from basics like the overall handling system down to the details for the cars and the fact there are always cars that turn up having the wrong exterior equipment for the version they are, which is partly Eden's fault, and partly Rabcat's fault since they make most of the cars. Eden doesn't have enough people to work and maintain a game this big, so they really need more people than they had for TDU1 and TDU2 to make a GOOD successor. Also an important link in this is Atari, they are the ones behind the rush, the odd bad carlist and the fact Eden had to go on a strike, so they also have to change dramatically. Add up the horrible community communications and the many promises they never lived up to, and go back to the beta which was followed by game release too quickly. After having played the game for months I still was not able to discover any improvements they made based on the feedback we gave them, more detailed than a dev could wish for. The betaforum was as big as the General Discussion section now is, and that was based on a small portion of the game! They shown to me they can't listen, they don't care, and rushing a title seems more important than taking your time. The servers are also offline too often recently, the game has hit the budget bins very early, this shouldn't have happened this early. Just look at the amount of people giving up on this game just 3 or 4 months after release. Is that normal? Maybe for a one-game-a-year EA-ish releaseprogramme.
Seeing how much TDU2 ''advanced'' from TDU1, and seeing as what Atari and Eden have done sofar to these two games, I have given up hope they can not only fix, but also over-compensate for these two games, with a brand new TDU3 game. It would only be possible if both companies fire all employees and putting in new ones, but that would be the same like just giving Atari some more undeserved money by letting a REAL developer/publisher combination buy the TD/TDU license, preferably NOT to EA I'd like to add.
