Assuming they do so, how many copies of Total War: Attila do you think Sega will report as being sold in their first post-release quarterly report?
For comparison, here are the sales reports following release of all Total War titles since Empire: Total War:
Empire: Total War - page 21, 810,000 units
Napoleon: Total War - not specified, presumably fewer than the 560,000 units the smallest 'major title' shipped on page 21
Total War: Shogun 2 - page 25, 600,000 units
Total War: Shogun 2 - Fall of the Samurai - not specified, presumably fewer than the 550,000 units the smallest 'major title' shipped on page 21, probably significantly less given that only 950,000 units were shipped in total across 5 PC titles (page 20), and the majority of those were probably Football Manager 2012 (page 21).
Total War: Rome II - page 18, 800,000 units.
