How much longer can MS continue with the "Xbone is outpacing 360 in its current life cycle" BS?

Revenue.  As stated in the NPD report.  People forget that the Xbox One was $150 more last year. Thats 30% less. So even if the Xbox One sold the same amount last year, revenue would have taken a huge hit. That combined with it selling less than last year means that the drop in revenue is modest. 

Until that statement would simply be a lie.

400k+ is worldwide not just in the US. According to VGC it sold around 200k+ in the US in its first week.

Also, 3DS is probabily undertracked.

“The launch of Bloodborne ranked as second overall in software sales this month, but also has the second highest sales for the debut month of a first-party game on the PS4, after inFamous: Second Son, in March 2014.”

The Last of Us Remastered- 272k

Bloodborne > 272k

From GAF.

For as long as the Xbox One keeps outpacing the 360 launches aligned.

Until it's not true.

But this isn't the 90s with the Genesis! It's not going to sell 100k extra systems in NA in 1 month. Alot of people where waiting for Bloodborne, and that came pout. Why would I buy a PS4 JUST because of Mortal Kombat. I know its still popular, but you gotta keep it real! So tell me, how will it move systems? Do you know anyone waiting for THIS game just to get a PS4?

My guess is revenue. Xb one down YoY (probably) with a $150 lower price tag means the Xb one contribution to over all hardware revenue is a major drag on revenue for the month.
