While Blue on Mac is still unavailable I'd like to point out that the same OGL 3D technology is released as 3D Objects for After Effects, Final Cut and Avid on both Mac and Windows platforms. Although 3D objects are limited to spline-based extrusions and primitive shapes they encompass most popular features of Boris Blue. 3D Objects are available as a separate unit or as part of BCC 6 package.
Sorry for not answering your question directly. But did you really expect a direct answer? Or perhaps just a rumor... anyone out there with a good rumor?
Thanks for the response. I have Red and BCC and like both of them a lot. There seems to be a few things my clients would like from Blue if I had it. I was just checking to see if there was any possible release dates or info available. Seems like a lot of users only use one platform and might be interested in the question.
