Is there a single feature that Microsoft could announce that would cement your purchase?
Halo.
I will be powerless to resist the next gen Xbox as soon as Halo is announced.
I've read every book, coo'd over every inch of every campaign.
The only thing that I find frustrating about all the rumours is that... Well... I know I am getting an Xbox for Halo... so it would make my life a lot easier if it did everything right (I don't mean GPU power in that either) so I can be a single format gamer next gen.
I have limited time as an adult and would rather focus that on enjoying experiences... the last couple of years I've had to rush through games when I have the time because my backlog is always bigger than I like. It's actually really stressful to have so many games competing for a finite amount of time.
This is the last generation of consoles and I want to savour every minute of it... I've been doing this for three decades.
So my current plan is:
Only buy one of them at launch and then pick the other one up... either:
1 - when Halo comes out if I decide to run with PS4
2 when PS4 comes down in prices and there's a good library of Sony first party games to be had on the cheap.
Right now, Xbox just has to be in the ballpark of PS4 for me to jump that way first... because I can integrate with Win 8 and my Lumia and stay connected... and while the core function of the platform is games (and I would
NEVER buy it if that wasn't the case), of late I've found a lot of the Xbox apps are useful - the GT TV, IGN and Gamespot Apps are getting a lot of use for watching previews and reviews.
Weirdly though, looking at raptr, I've used PS3 a lot more than Xbox this gen.
