I will agree to your second statement, no argument there.

But tegarding that logic of season, I'm sorry but I do not agree,since the time between season 1 and 2 was about a year, and the time between season 2 and 3 was about 2 years. We might even have to wait longer than 2 years, maybe 3 years since for every new season we have waited the number of years equal to the last season (season x = (x-1) years to wait).

But again this is all specullation and in the end ot all depends on the studio, the creator, the fans, and most importantly the popularity that DxD has at the moment.
