Really tempted to get the Age of Hannibal book but I haven't played Saga in ages and I am still working on my Normans and haven't started on my Aetius and Arthur collection... 
Same here, on pretty much all counts! (Though I have work-in-progress Vikings instead of Normans.)
How about the troops of Carthage, SteveBurt? From a screenshot on the webstore I see they have two flavours of Warriors (citizens or "contingents"), I'm guessing they'll be affected by different abilities on the board? Is it good to have a mix then, or are the non-citizens mainly useful for the additional options (cavalry with optional javelins)?
Just browsing the Victrix plastic boxes and thinking about which sets would be good to have... you know, just in case...
Of course, many of the allies could do double duty as the start of another faction too.
