Well, it sounds mostly like you're a huge fan of Blizzard's "When it's done!" release date philosophy.
I think what that really tells you is that these indie games seem to be more like a "labor of love" rather than some project working on a strict, well-planned schedule. Also, keep in mind that these are graphics and software people that are plotting out their schedule. In all of the work I've done, there's quite a bit of effort put into defining an adequate yet efficient schedule.
EDIT:
Although, I think the Super Meat Boy people learned about schedules
the hard way in the end!
