The following was announced by WOTC last week
Magic: The Gathering Tournament Rules Change: Extended
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.
Sword of the Meek is banned.
Hypergenesis is banned.
Note: The four cards previously on the banned list (Æther Vial, Disciple of the Vault, Sensei's Divining Top, and Skullclamp) are in sets that are no longer in the Extended format.
So with that in mind .... who would be interested in an Extended Event sooner rather than later in Grimsby ?
