Ok, now I've seen it, lol.
Ok... winter... so? Bear in mind that the wait is for the SG campaign mode, not for the gates themselves, for which there has been a release already, along with some other stuff. And if it takes time, it's for two reasons: 1- it's big. 2- the gates are still being refined.
Just have some patience, you've already seen how much the gate changes from the version currently released to the one that Frosty showed you in that vid, where you placed icons as gate addresses directly in the editor. You can guess how much time stuff like that takes to make. Actually, we have to be happy, this stuff is coming much faster than it did when we were still playing in OFP, mostly because a lot of ground was covered from the OFP gates.
Cheers
