Confirming the rumours following a trademark registration back in March, Bethesda has revealed that the first DLC for the hugely successful The Elder Scrolls V: Skyrim will be titled Dawnguard.

Disappointingly, the only thing accompanying the reveal is a teaser image that simply shows the regular Nordic Dragonborn archetype from plain-old Skyrim, however, there is one more detail that is likely to irk half of their fan-base:

Coming this summer to Xbox 360. More details at E3.

Yep, like the Fallout: New Vegas DLC, Dawnguard is expected to be exclusive to Xbox 360 for 30 days before it comes to PC and PlayStation 3.

Considering that Bethesda developers have noted in the past how Skyrim mods for the PC game can actually function on modded Xbox consoles -- highlighting that there is little difference in the content interface between platforms and would therefore be trivial to publish across all three simultaneously -- the only real conclusion that disappointed PC and PS3 owners can draw is that Microsoft has paid for the privilege.

Bethesda promises to tell us more about Dawnguard at the E3 expo in early June.
