Only 20/20 cricket could be included. Problem is, it's not really cricket. However, may increase interest al over the world. 20/20 will also give countries like USA, China (or any baseball playing nations) a chance to compete (after regional qualifiers). For us cricket fans, it'll just give us a sense of belonging and will give countries like BD and others an opportnity for medals if they make it an A team or Non-Pro event.
Other then that, there's no point draggging cricket into the olympics.
All that aside, I'd love to see ODIs in Olympics, but not sure if it'll fly.
