I hope to goodness they allow magic to crit while sneaking. While stealth kills are juicy and exactly my cup of tea, i really want to be able to surprise lighting bolt people and have it crit. I love nightblade characters in rpgs, it's just too bad they svck horribly in ES games.

Alteration and Illusion and Mysticism their chose, but thats is mean nothing now since Skyrim will have no classes and no mysticism school.
I think runes thats work like magical traps will suit better then thunder sparks of lighting or fiery flame balls for sneaky character, left such noisy and spectacular magic for spellswords and battle mages instead.
But some things like
