I think it would have made more sense to have still have Yoda and the councel deny permission to train Anakin and have Obiwan decide to train Anakin in secret. That would work much better with what OBiwan said in ROTJ "I took it apon myself to train him as a Jedi. I thought I could I train jedis just as well as Yoda could. I was wrong."

here is another thing that has always bothered me. In ESB Obi says that Yoda was " The jedi master who instucted me ". In TPM we find out it was really Quigon who trained Obiwan. I guess Lucas will have reedit the ESB so it fits his "original vision" right.
