I have a Campy Daytona BB with 3,000 miles on it. How many miles can I reasonably expect to get out of this component? I don't ride in the rain if that makes a difference. Just wondering if I will need to plan an upgrade soon.

With proper care and feeding....grzy mnky

...mostly forever. If it's going to fail it usually due to neglect and abuse. You shouldn't be planning on upgrading soon, but rather doing an "overhaul." Clean it up and get the debris out of the BB shell area - you'll be amazed how much crap finds it's way in there.
FWIW, I agree--I've never worn one out.cory

BBs last a loooong time, even with next-to-no maintenance. I don't keep close track of miles anymore, but I know the one in my used-to-be-best mountain bike, now a much-abused commuter/mud/snow ride, has been in there for 10 years. I've rebuilt several (new bearings and grease), and they rarely show significant wear.
Might be significant (but it might not) that I assemble them with boat trailer wheel bearing grease (5 bucks a big can at car parts places). It's a little thick, but it resists water and seems to hang around forever.
