It only impacted the vita and wiiu

How do you propose we make such a determination? How much higher would PS4 sales have been if not for the Switch's release and how do we calculate these?

And the 2nd highest is the "missed opportunity" Pro at $399.  MS cannot be happy that the Top XBO SKU is #121.  Fun fact, the Top SKU is only #32 in XBO products by themselves.  While the PS4 UC4 and Pro are both in the Top 20 for PS products.  May is not going to be a good month for XBO.  I'm thinking ~80K, while PS4 is probably going to be flat MOM.

Yep. It also helps when they keep them in stock, now.  Hopefully, Sony will have enough that they don't run out anymore.

I think they are playing to their company's strengths. Sony rules home consoles. Nintendo rules handhelds. I think they are appealing to different people. Or they offer a unique enough experience that people will get both.  I know I plan on getting one if they ever drop  to $150, possibly at $200.

The latter point is something MS struggles with, especially now that MS is focusing on PC, and why its losing so badly to the PS4.

Ps4 is beast mode!

And oke i agree ps4 / switch is a awesome combo

Well, we don't have the exact numbers, but apparently the PS4 has been up yoy over the last two months since Switch released. It will likely be down a bit this month (last year Uncharted 4 released in May) but if it's being negatively impacted, it's not yet showing in sales.
