The Dawnguard downloadable content pack for The Elder Scrolls V: Skyrim brought vampires, and the ability to become one with wings and super-human strength. It's unknown what's next for the near endless roleplaying game, but here are some potential ideas.

Flying Mounts

A pretty simple addition and probably as part of a bigger DLC content pack if it did happen, but the ability to ride flyable animals - rather than horses - would remove the need to fast travel and see Skyrim from a viewpoint normally impossible. Maybe Bethesda could sneak in a flyable dragon, rather than making players kill them all the time. There could even be a choice to kill or tame a dragon, just like saving or harvesting a Little Sister in BioShock.

Return to Morrowind

There's a gate in Skyrim which goes directly to Morrowind but is conveniently blocked by an invisible wall, as if Bethesda wants players to go there after a specific period. Morrowind is held highly by many, so a return two games later would be exciting.

The Snow Elf Prince, mentioned in a pre-Dawnguard patch, is buried in Morrowind. Could he be the reason for the return to Morrowind?

Spell Fusion

Wielding two spells in one hand is great and was long requested for the series. But, what if spells could be combined? Fire and lightning, together. Or get more creative with fire and poison, for example, so it's possible to burn and poison foes simultaneously.

Maybe Bethesda could expand the ability by having some kind of dedicated place for mixing spells, almost like potions, with new spells mappable to buttons. Not all spells could mix, so a bit of trial and error would be needed, like crafting in Guild Wars 2 where materials can be combined to discover new craftable items.

Interface Improvements

Trawling through items in Skyrim across a huge list is time consuming and inefficient. There's no way to search through items by keyword, favorite items for quick access (without button mapping), or sorting options such as damage or weight or value which is clearly defined. This would also need to be for the PC and Xbox 360.

Explore More

Setting another Elder Scrolls title in Morrowind could probably be done in its own game, so what about those areas that can't be reached (just as Dawnguard's vampire tower suddenly appeared in the DLC)? Skyrim is massive; there are plenty of towns and wilderness areas that could provide hours of content. Dawnguard is around 20 hours long.
