that's not entirely accurate.  Look at listwar.com to dispel this myth

With digital PS4 is probably far ahead. I mean it has at least 4 times the digital titles XB1 has (plus NPD already confirmed the digital market was considerably bigger on PS4...in the US, yep)

Tie ratio is hard to track now. I have bought 12 games, all digital for xbox one.

Unity is undertracked on X1. Its 1.5m in the US alone. Wouldn't doubt others being undertracked too.

I see no reason for the tie-ratio being different at all.

Actually I think its more the issue of overtracking in the rest of world area on PS4. Its tie ratio is so much higher then the rest O_O

True. Let me rephrase.   Considering that the ps4 was being bought not just by the hardcore fans but also by the masses, it's hardly surprising the the tie-ratio used to be lower than xbone's. 

What changed? The hype for ps4 is mostly gone so less casuals are buying ps4's only to buy a game or two.

Actually I wasn't exactly right. What I meant was PS4 has 4 times as many digital exclusives as XB1. That's still 2.2x as many as XB1

Regarding the NPD thing, I believe Aquamarine leaked it temporarily in Gaf's October NPD thread, but then deleted it when it leaked to other places.
