Ok guys, I have to say some things to bring clarity to this topic!
First of all, the gameplay
IS NOT PC, it is
PS4. This is no rumor or my opinion, I absolutely know it for sure!
Secondly, it looks quite good for PS4 Footage
You can absolutely trust me about it. Since I´m the game journalist they talk about in WatchDogs Q&A:

Also, we should speak more about the gameplay, which is the most imporant part and really "next-gen-gameplay"!
All the talks about Watch Dogs graphics are just complete bullshit, because it´s always like:
"Booooh, PS4-gameplay looks worse than high-end-PC gameplay!!!"
...oooh, what a suprise it is
I played the PS4-version for over 4,5 hours now and I can tell you, it´s very nice, the graphics are good and the gameplay is awesome.
I´m absolutely sure the PC Watchdogs will look terrific and really better than the E3 2012 demo. So let´s talk more about the gameplay and wait for the new official PC-gameplay!
