Could it be that EA has actually decided not to make a 5th edition of this game? Perhaps they see that the major difference would be tech specs, and not the content?
I like TS4 and I think the way it's structured allows for endless additions, because we never load more than a limited amount of the game content. The critical issue in my case - and I'm on an old low-end computer, is that I must avoid to fill up my harddrive because that is the biggest reason for game lagging. I'm still happily surprised when finding that adding a new pack doesn't impact much negatively on game performance (drop of fps I learned to accept years ago, but it's hardly got worse over the past 4 years and 10 added packs + loads of CC.
Of course, it all depends on what direction the team chooses. If they also improve on what we already got, I'll be glad. This was actually a major section in one of the past surveys. I'm eager to see both improved personalities and AI/awareness. And of course a new world, but I don't need a new world and 10 new dining chairs in every pack.
