The poll didn't have an option for me, either-- "Jumped ship, but swam back."
When I was shooting Canon, I still kept up with what Pentax was doing and was quite surprised by the hike in lens prices. Lenses that I had before I switched are now out of my budget. Saying that, I'm not terribly upset by it, though. In all reality, I really don't need a big bag full of expensive lenses when I can get the results that I want with a few mid-priced lenses. If you can't afford the shiny new expensive lenses, at least you've got the option of picking up older MF lenses that are just as good for a whole lot less.
Really, the Pentax system just fits me better. I'm loving my K5 and look forward to getting out and doing some "real" shooting with it soon. I loaded some test shots into Lightroom last night and was quite happy to find that they needed very little PP to look good. With Canon, it took me a good bit longer to get the results I wanted in LR. I'm especially pleased with the results I got at ISO 1600. Overall, the Pentax system is simply more intuitive.
Will I jump ship again? I don't plan to. Unless one of the other camera companies comes out with something absolutely amazing that I can't live without and could actually afford, I don't see any reason to switch. The gear I have will cover just about anything I might want to shoot. If it doesn't, then I can always rent a Canikon body and the appropriate lens/es for the particular photo outing.
Just my 2˘...
