Well, I managed to find some historical data for the XBone launch countries for which we got no leaks, if anyone is interested.
First to recap, per NPD via GAF 1.8M XBones had been sold in the US through 2013, and per MS 3M had been sold worldwide.
So we've got the 1.8M from NPD. We got leaked reports of 364K from UK, 126K from France, 100K from Germany, 36K from Spain, and 66K at launch from Australia.
So let's get to estimating. The US had doubled their launch numbers by the end of the year, so we'll go ahead and put Australia down for 130K. Looking at PS2 sales, we saw Canada sitting at 5-6% of the US, so we'll put them down for 103K. Ireland is about 5% of UK, which puts them at 18K. Brazil has about 1% of the Gen7 consoles in the wild, so we'll give MS the benefit of the doubt and assume they sold as many as 30K XBones.
Now it starts getting tougher to find numbers. Back in the PS2 days,
Mexico was running about 2% of the US installed base. I've heard they've doubled their overall video game spending since then, and I don't know how much of that was specifically spent on consoles, or how it compares to US spending since 2007, but we'll give them the benefit of the doubt and say 3% of US, or 54K.
I couldn't find anything for NZ specifically, but I found
this showing Gen7 numbers from mid-2008
for Australia and New Zealand combined and compared them to NPD for the same time. Long story short, compared to the US, they had 4.2% as many Wiis, 3.9% as many XB360s, 5.9% as many PS3s, and 4.4% as many consoles overall. Here's the problem, 4.4% of the US market is only about 80K units, and we
know 66K were sold in Australia, and we've already
estimated 130K for Australia, leaving roughly -50K to be sold in NZ. So, yeah. We may have overestimated Australia, especially since they sorta sound like PlayStation territory, but for now, I guess we'll give NZ the 14K we don't know for-sure were sold in Australia. So yeah, looking for any solid numbers anyone has from NZ. lol
I couldn't find any unit numbers for Italy, but I found
this which showed they spend about
half of what Germany spends on consoles, so it seems safe to put them down for 50K.
Last and apparently least is Austria.
I had to reach back to the PS1 era to find any firm info on them, but apparently a year after it launched, Austria was already
a quarter of a percent of the global market!! lol But that was a long time ago, so I'll put them down for a full percentage point, just like Brazil.
So where does that leave us? Well, we've got 1814K from NPD per GAF, so we'll assume that's a reasonably solid number. We've got our reports out of Europe and Australia totaling 692K, giving us 2506K consoles we can account for with reasonable certainty. My estimates for non-leaked countries total 299K, plus the post-launch 64K I gave Australia brings us to an estimated 363K units. That's 2869K, assuming I estimated correctly, and I think I was being fairly generous with my assumptions, particularly Australia.
That said, 100K either way may not seem like much to quibble over, but to hit 3M, you'd need to inflate my historical estimates by 36-65% to actually hit 3M depending on how badly I've overestimated Australia and I've already been giving countries significant bumps over their actual, referenced historical performance, like 4x sales in Austria. A 35-65% adjustment across the globe is a pretty significant shift in buying behavior with nothing in particular to explain it, so I'm inclined to believe such an adjustment isn't necessary. Particularly because of Australia, I'm inclined to call it ~2.8M in 2013, but we'll call it a "generous" 2850K for now.
So if they were at 1814K in the US in 2013, and 2850K worldwide, that would represent a concentration of almost 64% in the US. They're now up to 2.9M in the US, which would give them a worldwide number of 4.5M if they're at that same 64% concentration. If the anecdotes are true, and non-US sales have dropped off dramatically in 2014, further concentrating US sales to, say 69%, that would give them worldwide sales of 4.2M.
So I can say with reasonable confidence based on NPD, leaked Euro data, and historical data that XBone sales through June 2014 are probably in the 4.2-4.5M range, likely favoring the lower end, as non-US demand seems slight. That may sound harsh, but I tried to do all of my guesstimating in Microsoft's favor. Lemme know if anyone sees any glaring errors, has more data to add, etc.
