Major Extended changes

As many of you already know:

On July 1, 2010, the following sets will leave the Extended format: Ninth Edition, Mirrodin, Darksteel, Fifth Dawn, Champions of Kamigawa, Betrayers of Kamigawa, Saviors of Kamigawa, Ravnica: City of Guilds, Guildpact, Dissension, and Coldsnap. From that point forward, the Extended format will include approximately four years of Magic sets instead of seven.

At that time, the following sets will be legal in the Extended format: Time Spiral, Planar Chaos, Future Sight, Tenth Edition, Lorwyn, Morningtide, Shadowmoor, Eventide, Shards of Alara, Conflux, Alara Reborn, Magic 2010, Zendikar, Worldwake, and Rise of the Eldrazi.
With the upcoming release of Scars of Mirrodin, the following sets will leave the Extended format: Time Spiral, Planar Chaos, Future Sight, and Tenth Edition. One year's worth of releases will leave Extended with every subsequent fall Magic set.

I'll change the format legality of cards and decks next weekend (26 June) to reflect this.

As a relatively new player, I think I like these changes. Being just a bit larger than standards (2 blocks larger), it will make card price drops  lower on standard rotation, and new people will enjoy playing old standard decks again, without them being completely obliterated by the power level of extended.
