How was 13 better?

Well deserved, the game does feels a little incomplete but it was a enjoyable play through, however I enjoyed final fantasy 13-2 better and probably on par with 13.

FF13 is at 7.5M with Steam sales included.

Well they sold thru the 5M otherwise retailers wouldn't need another batch of discs. Supply and demand.

Its good that the FF franchise still shows good demand. We should still see FFXVI and FFVII soon.

Like i said, thats not always the case. If it were 7/8mil i agree with you but an extra mil doesnt guartee its sold through 5mil especially when that month is the holiday month (and includes digital). I do think 4mil has been sold but 5mil (still possible) isnt a lock. Youll see a better pictuee of this come npd

No offense but 10mil being an easy target means what your expecting 12mil-14mil lifetime? I think at this point 7mil is easy but im expecting 8.5mil-9mil lifetime (for now)

Amazing! 10M+ seems like a given imo. ^^

The stuff about an addition million unit order is conjecture and I think misrepresents what's in the actual press releases. Read for yoursef:

Press release 1

Press release 2

So on December 1, SE says that (Shipments + Digital Sales) has passed 5 million. 

On January 9, they say that (Shipments + Digital Sales) have passed 6 million.

It's possible that 40 days of digital sales is driving the growth while just seeing a marginal increse in new shipments. 

Honestly it's hard for me to believe that a game that has fluctuated between $35 and $50 new on Amazon and other retailers since a week after launch, and that GameStop was aggressively offering trade in bonuses for, is just burning through shipments. My gut (and brain) still says that it is a lukewarm reviewed JRPG released in 2016. 

I didn't care for it, but I'm happy that franchise is still going strong after 30 years.

I'm in the minority, but I enjoyed 13 way more than I did this game. Both were flawed, but at least FF13 gave me a real sense of progression, more fleshed-out characters that I could care about, an all-around great soundtrack (though FF15's soundtrack was good as well), and a much more aesthetically pleasing and fully realized universe. 15 was more open, but it was ultimately lifeless and filled with boring fetch quests and repetitive locales, along with some pretty dull set pieces. I just couldn't bring myself to like this game that much.

Is this a normal way of communicating numbers?

Like the first number was kind of bullshit, (putting sold and shipped together) this is a million more bullshit. Pardon the language.

This is just spinning numbers so we won't notice the company is very very disappointed with the sales and heads will roll.
