Yes, there's always something bigger and better around the corner...
That being said, I've used the FX1 on an HD show on the island of Koh Samui in Thailand, and it worked beautifully. Our DOP really liked it, and he's normally a feature film cameraman. I believe his quote was "The viewfinder as at the front where it should be!"
We got some great images off that camera, and it was very reliable. I'm sure you're going to love it.
Good Luck
