If something new is shown at EA Play regarding The Sims Franchise, what do you think it will be?

I'm a little confused with the whole TS5 idea. Didn't Graham said that now when the big Pets expansion pack is done, they can work on new exciting packs, or something like that? I don't now, I got impression that there's a lot to do with TS4 (and I think so myself), but everybody suddenly talks about TS5... Anyway, it'd be rather odd if they annouce now the game to come in few years, the Sims Mobile is not interesting to me at all, so I hope it's about a new expansion.
