I was just in Patong for 3 weeks, it was dead, dead dead. My girlfriends bar, she's the owner, is suffering horribely, sometimes they get no customers at all. The bar is off Soi Sansebai so not on the main strip, but she usually does really well. She said this is the worst low season she's had in 3 years. A lot of the bars are hanging on by a thread to stay open, some are months behind in rent.
With the way the economy is going in Europe, Greece getting a huge bailout with talks of Ireland getting another, and all the other issues going on, it doesn't bode well for tourists, anywhere, not just Thailand.
