To everyone above trying to justify the PS4 price as "the same" as the Xbox One's.
Consider this, most people do not want a camera, you might, that's great, have fun with that, but the majority don't and so Sony is saving us money by not bundling it.
Xbox Live Gold and PlayStation Plus are very similar now that it is required for multiplayer gaming however, Xbox Live Gold has been a rip off for the last couple of years and PlayStation Plus has more to it like discounted games and free games, they've been doing this since it was launched! so value there over Xbox as well.
Now onto the main feat, the price for a PlayStation 4 is £350 for an Xbox One it is £430 that's an £80 difference! that's quite alot, considering the PlayStation actually has the more powerful hardware and is a lot less restricted in terms of second hand games and internet connectivity.
They're also approaching Indie Developers, something I haven't seen evidence of on the Xbox One, Indie games are very fun little quirky cheap games that deserve to be heard, by excluding them from the Xbox, they are devaluing the console's ecosystem even more.
Now onto exclusive titles and DLC, This was actually a surprise that Microsoft managed to show as much as it did but Sony still had more to show, had more games in development and more exclusives from very well respected developers.
DLC is neither here nor there, I don't know anyone who would buy a console due to it having a 2 week earlier launch of DLC or exclusive DLC since the game devs are not going to unbalance their own game just for one console. So this doesn't really matter either way.
The last point is streaming services, Social Media and Ease of use.
So far, Microsoft's Xbox One does look very easy to use but we have not seen what Sony have so this is still up for discussion.
Streaming services PlayStation wins as you do not need a subscription to watch Netflix and Youtube which you do on the Xbox, again this makes the PlayStation even better value.
The PlayStation has a dedicated Share button and built-In hardware to share the last 15 minutes of whatever you've been playing, some may use it, some may not, either way, It could prove to be a pretty cool feature and straight to Youtube. The Xbox, well, does it even matter? The above reasons are enough I'm sure Social Media options between the consoles wouldn't sway anyone's mind to buy one over the other!
