CONFIRMED NUMBERS (Well, tecnically are estimate, but are 99% accurate)

XB1:

first week ~ 150,000

end of 2013 ~ 364,000

half of november 2015 > 1,000,000

We know that XB1+PS4 has sold 240k in the Black Friday week, and that XB1 beat PS4, so, XB1 > 120k in Black Friday. We also know both XB1 and PS4 has increase the sales by 120% combinet compared to the week before, so... around 50 / 60 k for XB1 the week ending 22 Nov 2014.

So, XB1 sales we can say that are some like ~ 170 / 180k in the week of 22 Nov and 29 Nov combinet, and we have for sure >1.17 million XB1 sold at the end of November 2014.

I said XB1 is at minimum 1.4m because as we know December is bigger than November, and we have XB1 at minimum 200k in November (170/180k the last two week ), so, with another >200k in December, we have XB1 at most likely >1.4m sold by end of 2014.

So, if the XB1 is at 1.65m or 1.6m sold, that's mean XB1 sold 200k to 250k in January to June 2015... (the first half of 2015)

Using VGChartz, XB1 has sold 245k (i said 265k before, sorry i was wrong) in the same period last year.

So, seem XB1 is down/flat YOY

For the PS4, well:

First week ~ 250,000

End of 2013 ~ 530,000

September 2014 > 1,000,000

May 2015 > 2,000,000

I'm learning good stuff from this thread, VGSenpai.

"Since Sept 2014

PS4: approx 1.1m  (1m to 2.1m)
One: approx 0.9m  (0.7m to 1.6m)

Humm, we know PS4 pass 1,000,000 by the week ending 6 September, is hard guess how are the sales by end of September... it can be close to 1.2m, also we have 0 guess for say how much sold XB1 in September. The only good estimate is that XB1 has outsold PS4 during the FIFA 15 week according to GameStop.

Since Nov 2014

PS4: approx 0.7m (1.4m to 2.1m)
One: approx 0.6m (1.0m to 1.6m)

XB1 is above 1,000,000 by the second week of November, not by all of November.

As i said, XB1 is at >120k during Black Friday, and other 50 / 60 k the week after 1 million annunced. So, XB1 is at >1.17 million by end of November 2014, that's mean XB1 sold between December 2014 and June 2015 around 400 to 480k most likely, not 600k... i dunno about PS4.

I think that is right?  I may be wrong."

Write above.

I think we could all be way off:

Read the full interview. 

He is clearly excluding the UK from that 70% and 90% number. 

Okay got you.
