Keynote Beta Movie Playback/Editing

Do you mean iWork for iCloud - Keynote Beta?

I'm not sure... but it sure would be nice! All I see is the "coming soon" verbiage... but can hope that it would be the next update!

All the iWork apps got iOS updates and Pages (Mac) recently got a .1 update – I can only assume Keynote and Numbers were just running behind schedule.
