Goal post move.
So you think no real world consumer is buying a PS4 as a secondary console?
Also secondary or primary, still competing for money and time. When multiplats come out you always buy them on both systems?
Some, but i think that's much rarer, as if they already have an Xbox then they already have access to a library of 90% (appox) the same games. I would love to see the actual figures
Its not a goal post move, its the core of the argument! If you think Switch is really eating into sales of PS4 and xbox, thats fine. I think they're growing the category and reaching dual owners and handheld players much more so, and would bet my lunch on this being the vast majority of their sales. Therefore not competing for the same dollars.
Edit: not sure I get the last comment, are you talking about software sales? In answer there are several multiplats I own on both ps4 OR xbox AND switch.
