Question about the new pages coming out?

So there is a post on macrumors that says that a new pages for iOS is in beta and coming out soon to work with icloud. For people that already have pages will it come as a free update or will it be a new pages that we have to pay for again?

I haven't heard any rumors but it will likely cost you the full amount. Apple charged the full amount for the iWork update for the Mac. (iWork 08 to iWork 09).
