Mounted Combat - With all the fanfare on this one it's almost a given. Face it, the majority want this...badly.
I could see this as being plausible, but we haven't even learned if mounts will even be in the game. They were so horrid in Oblivion (of which people were clear to point out), that they might have taken their usual approach to fixing something new. Which, in most cases, is just removing that feature all together.
Climbing - Again majority rules on this one and what better place than Skyrim (as trees and earth sore to new heights) to reintroduce this mechanic to the game. Rope and grapple makes a good excuse to reintroduce the crossbow too.
Again, this has already been confirmed as being out. Despite how advanced Skyrim's AI might be, almost ALL AI have problems with ladders. And even if they don't, it would be a very cheap exploit in the game, especially in combat scenarios (have a guard chase after you, climb up a ladder, while said guard is climbing up the ladder, strike at him).
Camping - I remember back in 07-08, a Beth dev commenting on the wonderful simplicity and practicality of the portable campsite mod. With the addition of a woodcutting mechanic and the presence of cooking as well it makes sense that building a fire would also be included. All that's missing is a spit ( :whisper: you'll get to forge that with smithing) for roasting meat and a bedroll that will let you rest in the wild.
Unless they balance this in some way (random encounters have a high chance of happening when sleeping in the wild), then I don't see camping happening just because it would remove the need for inns and make the purpose for said place useless. Why pay 20 gold a night to sleep in Winterhold when you can just buy a bedroll for 10 gold and sleep outside the city limits any time you want, no?
As for my take on what we'll see, I have some general ideas.
- More in depth anolysis of the new Radiant AI system.
- Further demonstration of the Radiant Story and new conversation system in action.
- Demonstration of the new combat system, featuring weapons such as the longsword (perhaps with shield to show off shield mechanics), dual wielded long swords, dual wielding short sword and long sword (to show the difference), bow, and possible polearm (spear, halberd, etc). I would put the possibility of crossbows, but seeing as they overhauled how the bow works, adding in crossbows would only negate the need to use bows at all.
- Demonstration of the new magic system (perhaps tied in with the new combat system)
- Perhaps a demonstration of the new UI
- While all this is happening, they'll be talking about the new graphical features that the new engine presents.
- And (I'm calling this right now), to finish it all off, the PC will fight a dragon.
