The below info is mainly from, I believe, the December 2011 edition of PC Gamer, but has also been discussed in several other places. Some of the information is new to me; some is not.
Numbers of levels the game is balanced to: 50.
Maximum level attainable: 70.
Total number of perks: 280.
Approximate hours needed to reach 93 of the 280 perks: 1,000!
Damage multiplier for sneak-attack backstab: 10 (although I read somewhere else that it was higher).
Number of caves and dungeons: 150
