Although is will support that many players, it doesn't HAVE to. I am sure you will be able to determine those kind of variables when you create a game.
Yeah, you should be able to do that. But it's just like what's the point to have 64 players? Kinda like how the PS3 supports up to 7 wireless controllers. (Do they still support 7 wireless controllers?) I think 64 players might be cool if they have like, 8 man squads or something. So, there's 64 players, but your 8 guys have to take this position have to do such and such to allow another squad on your team to do such and such. And have them almost kinda separated or far enough away. If you just have 32 people on each team, on a decent-sized map, it's just not that fun.
7 devices, which means one day perhaps mutliple things like a mouse keyboard and headset. For 2 people that would be 6 devices. At least, that is how I understand it.
ah, 7 devices. that's a little different. i think i originally back at launch someone saying, "The PS3 can support up to 7 wireless controllers!" And I remember thinking, "Wow... that's great... for all those 7-player split-screen games..." that'd be cool if they come out with some games that actually utilize 7 devices. like... a pair of boxing gloves! or something...
The whole "7 controllers at the same time" was, in my opinion, another attempt by sony to beat MS to the numbers, like when they said "the PS3 will run at 1080p" right after MS mentioned the X360 would run at 720p.
Doesnt Pro Evo (and or other sports games) on the Ps3 support more than 4 players? I recall some Saturn games did, up to 12 was it?
I cant recall the names, but I think one bomberman game supported dual six-player adaptors, therefore up to 12 players.
Whilst there probably can be said to have been a numbers game at play in general, I think mairsil is quite correct on this - bluetooth allows ad-hoc networks to be formed from 8 devices, with 1 (in this case the PS3) acting as a master, with the other 7 as slaves. So the 7 was probably more the technical result of the decision to use bluetooth, than any marketing largess.
