The Elder Scrolls IV: Oblivion Downloadable Content

Bethesda has released a new downloadable "Horse Armor Pack" on the Xbox 360 Marketplace, which allows players to purchase Elven and Steel armor for their horse after shelling out 200 Microsoft Points. A few more details about the update can be gleaned from Xbox.com, but I can't help but feel that us PC players are getting neglected. Can't we afford $2.50 for a nifty update like this?
