It's pretty much 60:40 rogue vs druid if both are equally good and have equal gear. The feral can't kill you while evasion & combat readiness are up (30-50seconds) and you can't kill him while survival instincts are up, though you might be able to through barkskin. None of you should be able to restealth and the druid shouldn't be able to go back to caster form and use hots.
I'd put my money on the rogue just because he always gets the opener personally, but I can also see the druid managing a win, albeit with some difficulty.
The next patch is probably going to make this battle slightly more in favor of the rogue, 65-35 or thereabouts but still very possible to win as both classes.
