The starting area for Goblins is kinda fucked right now so, looking over at my Rogue (my main character on Argent Dawn), here's what I noticed.
These are my current stats in Lich King. This is with decent gear, but it's all stuff from Heroic 5-mans or lower (no raids).

Copying this character over to the Cataclysm beta, I have these stats (after speccing as close to my current live spec as possible).

Important things to note are the +300 points of Agility and +500 (and change) Stamina. Yeah, I have 5000 more hps on the beta version. However, even though my Agility went up (and so did my attack power), my damage actually went down slighty.
Crit chance went up. Hit chance stayed roughly the same, I believe, because the Cataclysm stat window shows your hit chance from all effects, not just hit rating on your gear.
So, it's something to think about.
Want something else to think about?
THESE are the stats on a level 85 pre-made in blues.

This rogue, by the way, has almost 81000 hps. And that stat-line is completed unenchanted/ungemmed/unmodified by any profession blues. So while he's missing haste, and hit rating, those aren't going to be as bad in live as they look. So yeah, it's only going to go up.
