So, it takes about a year. it's a pity.
No, Kurt, not exactly a year, we're lucky to that extend that we don't have to create all new models for everything ( trees, houses, statics, vehicles, weapons ) as some of those are done with a snowy re-texture.
The update will be this year, anything else would be silly. I'd even go as far as say it'll be on this half of the year. However I simply can't say when the update will come 'cause:
1. I simply don't know
2. if I'd promise a specific date and we'd miss it, everyone would get mad and disappointed.
3. And I'd most probably miss-guess the specific date because of number 1.
