If I already have Mark 12, do I just need to dl part 1 & 2 of the new version and rename the rest? is there a quality change that will make it worthwhile?
Will there be an eventual update to include an update to the part for Iron Man 1 where the video freezes when Tony does the first test run of the suit?
That will also be fixed in Mk 15!

You are correct, you'll need to download new parts 1&2, while renaming old 2-19 to 3-20.
Old Part 20 (new Part 21/Infinity War) will have updates. And of course Part 22 will be Endgame
