Well, I personally would prefer getting the source, because there could be many more bugfixes and improvements and I would be able to have a go at it myself. But TB never promised to release the source, he was just thinking about it. So if we get some bugfixes and updates I'll be more than happy about that, a bird in the hand is better than two in the bush...
(in Spain we are more radical with that, we say "a bird in the hand is better than a hundred flying)
