I've had a few, but only 5-6. They're about as rare as an Ice Golem it seems.My only problem is that the Sand Elemental doesn't seem to be spawning during a SandStorm for me. I've tried multiple different world in hardmode but I can't seem to find any. Other then that, I'm impressed! You guys did a great job with this update and I can't wait for 1.3.5+ to be added later on.
