It seems like a number of apps will probably do this. For instance, I can't find Twitter for Mac outside of the app store, which is disappointing because I'm still on Leopard, stuck with Tweetie 1.2.8. I would say to be wary of losing your Leopard user-base, but being on the Mac App Store probably will give you enough exposure that you'll make up for it and more.
I think there's not much benefit of staying on Leopard if you run an Intel Mac these days. The upgrade cost is pretty cheap, and the benefits do developers are quite heavenly.
I've been keeping Leopard support in TapeDeck because it's been pretty easy to do so, but with the work I'm doing on 1.4 right now, I've been tempted to hit that kill switch...(But I won't.)
