If properly cared for, and under common urban all-weather cycling conditions, yeah your chain is going to last for more than a few weeks. 1500 miles is what I get on my 12sp MTB chains, which get exposed to more severe service than urban bikes do. I have taken a chain from new to letting the .5 gauge barely slip through on the chain checker in about a week though. It required riding through all manner of mud and crap for about 18 hours a day during an ultradistance race.
