I am really excited for this game. But, I have to agree as well. Let's fix issues instead of cranking out new games so soon.
I think it'll be fun though. Hopefully, some new skills and careers. And, I don't know if I want a new town, or if I want the pets in SV, TB, & RB. Also, I was thinking with WA it'd be cool to see what animals you could see/buy in the three worlds!!
Also, I was a huge fan of university. It'd be great to get that again, as either its own expansion or as part of another one!!
But, overall, I'm excited for pets!!
