Wheeee!
#8 sounds especially good to me.
I've always loved underwater exploration in RPGs, but previous TES games were somewhat disappointing in regards to underwater content.
I loved underwater exploration in Morrowind. I must have cleaned the whole island of pearls. It's too bad underwater exploration in Oblivion was so poor in comparison. It was a BIG letdown for me...
I hope there is a swimming skill and waterbreathing spell.
