Bold: That already mean 

That's your perspective. Mine is a sequel spin off when time travel is involved. Doesn't really matter either way since it's not the actual prequel

Agree to disagree, then.

So... Looks like it was indeed overshipped at first. 0.5 mil for the rest of the holiday is pretty low considering the initial shipment.

That should still make it Koei Tecmo's best selling game though, so it's a pretty big succes regardless.

Had they not told us the initial shipment, I do think this would seem more impressive, as it's still the best selling musou game ever and did pretty well overall. It should pass 5m with ease, although sales could drop off quickly with a game like this so it's hard to say how far past that it'll go.

Pardon my ignorance but does "shipped" include any digital sales?

In general, yes, unless specified that they're only talking about physical sales.

Now this is what I call a severe case of overshipping

Why overshipping?

Maybe I'm understanding wrongly but didn't they ship like 3 million in 4 days and then only 0.5 million more after those few days and until the quarter ended?
