I am going to list my thoughts here instead of making a new thread:
Both systems show a lot of promise and with drastically different approaches for the next gen in gaming...
I think out the gate the PS4 is going to be the winner here due to the 8gb of DDR5. That said, here is something to consider, with the heavier emphasis of cloud computing on the X1, it could potentially become more powerful as time goes on and internet speeds get faster.
Even though the X1 is more expensive it does include the Kinect while the PS4 does not include their camera which is $50 from what I have read. It is also much less advanced from what I can tell. However, this is just an opinion so dont judge based on those comments.
I personally like the idea of being able to control my DVR and satelite box through my game system with gestures and my voice. I have a universal remote currently and it is a pain in the butt. However, without it I would be juggling about 3 remotes every day and 4 when I wanted to watch a movie.
It also looks to me like the media available through the XBL is better than that of what they are proposing through PSN currently. Seeing as how they are now going to be both padi services I expect to have better content and XBL has a lead in this but that should be expected considering their online model has been similar for a longer period of time.
I also like the other features that the X1 adds such as the side by side stuff for watching movies and playing games and such.
the PSN looks like it is going to be playing catchup with the other media features and I think it would be too early to judge this right now. However, I will say that it looks like they are definitly willing to step up to the plate.
PS4 is the obvious winner here but I think it is funny how no one has mentioned that many of the developers have already been implementing their own DRM for used games. Look at Uncharted where you have to buy a new Online access key if you buy the game used...however, the fact that anyone can loan single player games out to friends is still better than what the X1 is currently offering.
Now for the X1, it certainly seems to be implementing alot of problems. However, it sounds like you can loan your games to up to 10 people without issue. This is a non issue to me as I pretty much NEVER loan games as too many times I have gotten them back broken/damaged.
However, I personally dont care about this much to begin with as the majority of my games are bought digitally on my PC and my more casual gaming is done on consoles with my wife.
Games announced at E3:
Personally, I think the X1 games looked much more appealing than the PS4 games. The only one that really looked great to me was Destiny on the PS4 but other than that there was nothing that made me go "wow".
On the flip side the X1 had Project Spark, Ryse, and Dead Rising 3.
I personally give the hand to the X1 as well. But that is really personal preference.
that is where I stand now with these two systems. I would like to note that I may decide to not get either as I mainly use my PS3 now as a bluray player and I dont even have a 360. When I play games they are mainly on computer but me and my wife do enjoy gaming together at times.
