I don't think so. At the time of writing, they're close to a $100k in sales with many more days still to go. If you multiply that by the average developer share you'll end up above $10k per indie dev (that number also is going to go up significantly over the next days). That makes Humblebundle a nice bonus for developers who already invested their time into making these games. Equally important, it gives them exposure to an audience who might otherwise not have tried those games at all.
