Its the end of one era and the start of a new one.
The date is official (for now) for World of Warcraft's next big patch (3.0) that will bring all of the new talent trees, the inscription skill and it will mark the end of the last Burning Crusade Arena season. The magic date is interesting in that it follows the weekend after Blizzcon and is almost exactly one month prior to the launch of the expansion Wrath of the Lich King. From the official forum:
WeÂre currently planning to end the fourth Arena season on October 14, 2008, and as always -- this date could easily change. This Arena Season is only ending in respect to the ladder, meaning we'll be taking a snapshot of the season's ladder and then go through our normal process to determine who is eligible for the end-of-season rewards. This process should take approximately one week. It's very important for players who feel that they may be eligible for the arena-specific title and/or Armored Nether Drake to refrain from transferring their character to another realm between the date outlined above, and when the end-of-season rewards are physically awarded.
Upon the end of this Arena Season, teams and ratings will not be wiped, and will carry forward allowing players to earn points each week and purchase gear until the launch of the expansion (November 13, 2008).
You may recall that yesterday they announced they would not wipe honor points, but honor items will be significantly more expensive for level 80 character (oh joy). If this stays on track, the expansion looks golden for six weeks from now. Yes, a scant six weeks from now I'll be asking where you will be standing at midnight. Until then, enjoy your new talents and I hope you got that Zul A'man bear mount.
