Accept nothing until it is announced. Even that little clip makes the prequels tie in together a little better.

Now if we could just also have them reshoot TPM with no Qui-gon, and have Obi and a teenage Anakin be the ones who are sent to Naboo, we would have ourselves a great movie. Most of the major plot lines could be the same. Have Anakin who is roughly the same age as Padme impress her with his abilities. Somehow they are seperated from the rest of the group(similar to how they were alone in attack of the clones) and we would have a believeable relationship. You could even have them dislike each other for the first 1/2 or 3/4 of the film.
