Who wants Seasons to be the next expansion after Cats and Dogs?

What, may I ask, is Frostbyte3? I wonder if some sort of 'guys, this is all we can do with the engine we have to work with' post by one of the gurus would cut down a lot of the griping, etc. on the forums. A lot of it comes across as, 'we had X before, so why not now?' apparently assuming the current engine (like those before it) can handle it. It's a whole other thing if the current engine is why we don't have X, and if folks knew that maybe it would be more peaceful around here.
