exclusive marketing is more about growing mind share and awarness for the platform. if every game had xbox one after its trailer then the awarness and mind share would be much stronger for xbox one. 

sony and ms are marketing their consoles through these games, so its effect isnt massive once these games drop. its a continues process to grab mind share. so the result isnt a huge spike at once. bundles do help though. 

XB1 looks pretty strong in UK.

PS3 gamers have moved on quickly judging by that 4%, although that is to be expected as people were more satisfied with the 360.

I have a feeling the gap between PS4 and X1 versions will grow over time like Watchdogs.

As for whether or not the excluive marketing helped, I think we should wait for hardware numbers for that one, especially from the US.

OP updated with official individual, all formats charts.

Or C) PS4 owners buy more games digitally!

both PS4 and XB1 are pretty much spot on when it comes to official numbers. 20k~ or so off mark. 

@bolded: it only takes a look at sales numbers to realize that. also, 360 sold 3m more than PS3 in the UK. 

Why would it be highly unlikely? It seems to me very likely, as PS users are used to download games monthly because of PS+. It seems like a very valid reason for the narrower gap than expected.

PS4 a bit over tracked. by 20k~ or something. xb1 its hard to say whether its under or over, because we know just the ratio with PS4. but its in the same ballpark. 

That works both ways. X1 + Destiny was 349 everywhere. Game even had Halo: MCC with it for the same. Amazon had £35 Destiny Expansion DLC with it.

Seems like a good thing for PS4 as people often buy what their friends already own and switching console brands each gen seems like common practice for British and American gamers.
