Wouldn't you rather want to reuse your existing artwork by renaming your files? Ideally MC would have an option to do that for you, although there are several other ways to do that manually or semi-automatically.

An ideal situation would be to have the option in MC to either re-name existing artwork, copy existing artwork and re-name but keep the original, or delete pre-frodo artwork (if you've already taken the second option in the past).
That way anybody still using (pre-)Eden or xbox can scrape for (post-)Frodo and their older builds, and delete un-needed files when (if) they move on.
As for me, I'll take whatever the devs dish out and be glad to have it - I love this program!
