There has been no official announcement.
All I can say is that if you ordered a unit, don't order a sway bar until you pick up your unit. As I have mentioned on here before we do a lot of running changes so we're not trying to time everything at once. We do not charge existing orders for those changes, so if you get them great, it's a bonus. If you do not, you didn't pay for them in the first place.
Sorry to be cryptic, but if I put something on here officially then I'll get a hundred warranty claims saying "their unit did not have the sway bar that was promised by bclemens on some forum somewhere". Right now the current brochure does not show it as standard. The 2017 brochure will certainly have it listed as standard. Units coming offline around mid April may have a sway bar on them...but again, that is not listed in the specs so it would simply be a nice "value added" item. We're always trying to make the product just a little bit better.
