Iiliad is a bit of a myth - some author even believes that it is in England (Celts), which is reasonable because simply, Celts do have the numbers (Greece was only more populated AFTER the the story), loves their chariots to boots and all the XXXX places in Greece/Turkey just don't fit! too much argument, imho, so best to avoid it.

however, Napoleanic Invasion as an ETW expansion will be more than reasonable. I am hoping that they will cover several mini campaigns -

India Campaign
Napolean Campaign(of course)
Nth/Mid American Campaign (French, British, American, Spanish)
Great Northern War Campaign (not sure - i might have been too late)

remember good old Master of Magic? if CA decided to go into fantasy, and do it properly, they will find alot of Master-of-Magic fans.
