A winter vacation pack was the first thing that came to my mind when I saw the yeti costume, mainly because it made me think of the bear costume from Outdoor Retreat. This would be lovely! I've always wanted a world of eternal winter, like an ice desert in contrast to Oasis Springs, which is basically a world of eternal summer, and even though I was hoping for a residential world, a vacation destination would be the next best thing... or better yet, a world that is divided into a residential and a vacation area.
If we do get a winter-related pack, though, I wonder how the weather will be implemented. Winter and snow are concepts introduced with Seasons, so how will the 4 or 5 people who haven't bought Seasons yet experience this potential new pack without it?
