If both the action bar and the macro bar will be unified, will we have to set the macros for each class independently? Also, for macros that change jobs, this could take up an entire bar. How many bars will there be? Just the three, or will there be an endless cycle? I'm just a little wary about the amount of space my macros will take up - right now my actions take up three bars, so trying to fit in about 30 macros on top of that into a mere 30 slots will prove tricky to say the least.

I know "a large amount of slots to play with" was mentioned, but obviously if 30 are displayed at once then it would take a significant amount of cycling through bars to reach certain things, personally I'm kind of happy just having to press Ctrl ^_^:
