I think those are some pretty good predictions.
I guess I'm hoping for a bit of a strange thing but I actually don't want them to release a pack in January, I have never liked that month as a time for releasing a pack because I can imagine it must be pretty difficult for Maxis to finish the pack before and after the holiday which could result in less time for them to make the pack good.
This year we will probably see the effects of the developers working from home as well. I would not be surprised if EA still wants them to release the same amount of packs, which could result in them having to cutting corners somewhere else, like in what content that there will be in these packs.
