Etherealness beats it. And although Blink doesn't completely defeat it, it DOES allow rogues to sneak attack creatures with Blindsight, assuming the other conditions (not immune, no concealment, etc.) are met. I think a blinking rogue should have a 50% chance of successfully hiding, since they are only detectable 50% of the time (while ethereal, they are scentless, noiseless, and invisible to all in the material plane unless viewed by trueseeing and perhaps a few other tricks).
