I'm gonna spend around £920 on Xbox one at launch date with 8 games which they are bf4 , cod ghost , forza 5 , dead rising 3 , Ryse , need for speed , watch dog and assassins creed 4 , extra controller and play & charge kit :) 

I will spend about 0$

£450 for PS4 + Camera + extra controller + Killzone Shadow Fall
£50 for each of Watch_Dogs, AC IV and FIFA 14

£600 total

I'm holding off on Need for Speed Rivals cause that seems like a lot of money and a lot of open world games

Damn OP, you're going in hard

Let's see, for me.....I guess it'll be like between 700-760 Euro.
That's X1 with Fifa included
A play and charge kit
Battlefield 4, Ryse, Forza 5, and maybe Dead Rising 3 (I may put that one off for a little while though, as I won't be able to play everything at once anyway)

Xbox One: 499,- €
Ryse: 59,- €
Dead Rising: 59,- €
Call of Duty Ghosts: 59,- €
Fifa 14: FREE.

Nada

Gonna YLOD my PS3 and get an exchange voucher for £150 and by XBO games with that.

Not going to spend to much because I plan on buying a Note 3 and Kindle HDX 8.9 around the same time.

PS4: INR 32,000($640)
Killzone SF, Watch Dogs, FIFA 14, Battlefield 4, Drive Club: INR 3000($60) each
Total: INR 47,250($945) with shipping charges.

0€ if I'm one of the Upload Outreach winners (dreaming is tax-free), if not...

700€: Xbox One (I guess I'm to late for a free Fifa), Battlefield 4, Forza 5, Ryse/Dead Rising 3 and Killer Instinct.

PS4 + Killzone Shadowfall = $460 + tax.
