Will new MacBook Airs get free upgrade to Mavericks?

Am I correct in remembering that people who ordered new MacBooks after their release at WWDC 2012 received a free upgrade to Mountain Lion whenever ML was released to the public? If I am correct in my memory (I really hope I didn't just make that up), has anything been said about people who just ordered the new Haswell MacBook Airs also receiving a free upgrade to Mavericks when it's released? I ordered a new Air after WWDC, and the prospect of paying to upgrade to Mavericks in a few months time doesn't appeal to me very much. Thank you!
