How about ACAD for Linux. Then I could drop windows al together. (remember the days R12 for UNIX)
Like Chuck said, "ain't gonna happen". ADESK and MS are joined at the hip, virtually married, or what you want to call it. The best we can hope for is a open source alternative. Don't see that happening any time soon either but it's a nice dream.
I would like to see a lower price tag myself, say $1000 or less, then maybe some of us poor folks could afford it.
Man ... talk about your pipe dream ...
