I'm worried that the game will not live up to expectations. Multiplayer is not interesting to me, and after the launch of the sims 4, they really need to step up their game. Hopefully whatever big new feature they implement won't be a disappointment (like emotions in the sims 4).
In my opinion they should make the sims 5 a combination of sims 2 gameplay, sims 3 open worlds, and sims 4 CAS & build/buy (but with the Cast tools from the sims 3). Furthermore, they could look at paralives as well as farm simulator games for more ideas.
Paralives has some cool features such as reordering the action cue, resizing objects, heterochromia, placing tatooes anywhere etc. Furthermore the sims should look at games like runefactory 4 and my time at sandrock which do a great job of making the town come to life with special holidays, festivals, competitions, etc.
Technology has advanced a lot since the sims 3, and if EA puts the work into it, the sims 5 could have a really fun open world (or at least open neighborhood) where not only do sims feel alive, but the town does with store sales, holidays, festivals, etc.
