This just in, the Mac App Store will not wait for Mac Lion after all, it will be made available to Snow Leopard!

Best place to discover apps.
One click downloads.
Auto app updates.
Free and paid apps with a 70 / 30 split.

OSX Lion: multi-touch apps, app-store, full-screen apps, auto-save, apps resume when launched. Cool!
