Short of that:
Chances are arms will fare better in cataclysm, and won't be COMPLETELY useless compared to how it is at the moment. In cata, with the availability of mastery, you can get your Strikes of Opportunity up to a pretty nice proc rate. Eventually we'll probably be getting 40%+ Mastery proc chances.
Blizz seems like they want to make arms work in PVE, so heres hoping.
Right now, in heroics on the beta I'm beating everyone I run into as arms, which makes me happy. However, I'm chalking this up to people being stupid/terrible/etc.
In PvP, we're still doing good- just really reliant on a healer.
Also, TSG is going to be hilarious in cata.
