Much quicker out of the starting gates
The December 2007 DCI Banned and Restricted List announcement is up. It's mostly irrelevant to me, featuring a bunch of bannings in online formats (e.g. every transmute card is banned in Prismatic, where tutors are inherently overpowered). The interesting bit for Magic in general is the shift in when cards become legal for Constructed play. Previously, the policy was that sets became legal on the next 20th of the month (whenever that happened) following the release.
This year, that led to the super-quirk that Future Sight became Constructed legal on the second day of GP Strasbourg (which, of course, meant it wasn't legal, since you don't get to switch out decks if you make day two). This new policy doesn't inherently reduce the chances of that happening again, but it does mean that there won't be this annoying situation of knowing that the format is about to change, possibly dramatically, but having to go with the old one anyway.
That said, it's going to lead to quite a few more disqualifications if any event comes right on the heels of a set release that rolls a block out of legality. This year's Amateur National Championship came a week after Tenth Edition became Constructed legal (and thus a couple weeks after it was released!) and I still ended up game lossing my second round opponent because he had cards in his deck that rolled out when Ninth went away. The prospect of, say, a GP that starts on the Saturday following the introduction of a new block is pretty daunting, organizationally (although it would be great to see what people took into such a completely unknown environment -- even GP Krakow benefited from the results from this years' stock of States/Champs events).
