I have read the entire thread, and I am still a little confused.
If I have ONLY 2.2.0 Open Alpha installed, and DO NOT want to install any version of 1.5, I just need to wait for the 2.5 Release version, and I can update directly from 2.2.0 to 2.5, is this correct?
I have about 87 GB free on my SSD with 2.2.0 and Nevada and Normandy installed, I am not sure I have enough room to add 1.5.8 AND then 2.5. Suggestions?
