That's still quite low. Nusco - Any mod author has the full moral right to go commercial. Some players might complain, but all this thing about mods becoming commercial products should be very exciting for everyone. It looks like the early 80s, when two guys in a garage could come up with a blockbuster game in their spare time. In the 90s, it was either a big production with a big team or nothing.
Mods mean power to the people - again.
Making a mod and going commercial is just one route to take the big producers' noses out of the creative process. If Minh, the author of Counter-Strike, can go commercial and give us more of his vision, unadulterated by production constraints, then that's good for me. We're already working on other parallel projects. We'll support Holy Wars after release as long as people like it. Because Valve supports mod authors in a way no other company even remotely does.
