Back in November, the Fusion 360 and Fusion 360 Ultimate roadmap was published, giving an insider's look into the development of Autodesk Fusion and when specific enhancements will be released to the public in the coming year.
Recently, Autodesk revised its roadmap and pushed out the December release date to January 15. Since it is only a week away, let's hope the date is an actual target. Considering that the next date is February 12th, it appears that Autodesk is using Thursdays as the magic cloud-update day so the 15th may be a date you can count on, although not exactly on the 6 week update schedule implied in the post.
From what I can tell, Fusion 360 is gaining a lot of features pretty quickly. I'm personally happy I invested in the Ultimate deal that was offered at the end of last year. Fusion 360 Ultimate is highly focused on helping designers collaborate, innovate, and explore.
