kodeen: Well it's slightly more powerful, but probably not enough to matter. I think that it'll be, like this generation, down to your personal tastes in the exclusives. Personally I find the Infamous games to be a hoot, so I'll still be getting a PS4. Maybe an X1 at some point, but I never got around to getting a 360, so that might tell you something.
McDon: I thought the Xbox one was more powerful? Least according to Xboxians who used that response all the time when Sonyers attacked the DRM policies. Don't have a clue myself, not into techy stuff, just the games.
Here are the differences I'm aware of, but it's mostly rumors and speculation:
1) While the CPU has the same 8-core count and clock speed, Microsoft confirmed that 5 cores would be available for X1 games while the rumor was that PS4 games could use 7 cores.
2) Confirmed - X1's DDR3 vs. PS4's GDDR5. I don't know exactly how much of a difference this makes.
3) Supposedly the PS4 GPU is based off of a higher version 7000 series than the X1's GPU
kodeen: Thoughts are that this could kill the family plan, which seems reasonable to me since I don't see how they can continue that feature without verifying you still own a game.
Cameron: Yea they stated the disc will now need to be in the tray while playing. Sounds like the family sharing is likely dead. Too bad, I liked the concept a lot and I don't support used games so it was a nice feature for me.
I didn't even think about this, but reading the official announcement they are killing off family sharing for XBLA games, which you would think they could retain ...
