I am pretty sure there will not be a Winter Vacation - as they are not likely to do another dlc for dlc after MFP fiasco with simmers carrying on - nor are they likely to do another pack with just winter - as then there will be people yelling about that being a feature they already had - so either way I don't see that dream coming true.
As Sims 1 did not have a seasons pack ever they instead introduced weather just in Vacation worlds - they had the winter lodge - the fall /Autumn camping, and the summer beach vacations - but the sims world never had weather. Believe me you could have some of the winter stuff for your lot and igloos and half pipes look darn silly without snow. I did like the metal detector though from the winter lodge stuff - at least that did not look odd in the regular world.
The only somewhat weather kind of pack I could actually see being possible because it will not really need Seasons so no dlc for dlc and because certain things were missing in the actual seasons pack would be a beach vacation pack in which they could add the so called missing things from summer to that kind of pack - like lounge chairs, tanning, ocean swimming, maybe even lake swimming, water toys and games - Resorts, Motels etc, etc.
They could do that kind of pack without crossing any lines that would raise too many simmers ire - well outside of the ones who will always complain - it should have been in the Seasons pack. I guess there is no way to avoid those complaints - just hope it is not loud enough to make them change their minds about doing such a pack if that is something you all want. But a winter pack to me does not look like something they would do because all of the above. Maybe at one time they considered it - but for those reasons - I'd be surprised if they delivered it - but I feel a beach pack could still be possible.
