I think having basic weather/seasons in the base game is ideal.
I think seasons is a beloved addition to the game ... I personally wasn't entirely fond of Seasons either, though I am talking about TS2. I loved the addition and it was really cool, but I wasn't necessarily a "seasons" person. That being said, I did turn my town to go between Summer/Fall a lot. And I would also mimic the seasons as they were happening in real life. I'm in Canada, and we experience everything, so that was cool.
I want University more than I want Seasons though. But a majority of people seem to want Seasons. Hopefully EA can pull it off ... honestly, I would have more faith if Seasons was released as a GP rather than an EP. Their EP team seems to fail in a lot of ways, and the GP's - to me - have the best design and innovation.
