Xone or Ps4?

Is there party chat on PS4?

Yes, up to 8 people can chat at once as well as to Vita players

Are the services such as Lovefilm, netflix subscription free on PSN now? (Do I have to pay for subscription to those services separately on top of PSN+?)

Well you don't have to have PS+ to use Netflix or any app on PS4 but obviously you have to pay to use the service in the first place.

What IP's are in the pipework (I am no fan of inFamous or Killzone so those don't interest me in particular, liked Uncharted & Heavy rain though)

Naughty Dog's 1 team has been on hiatus for over 2 years so they have something cooking (haven't made anything since Uncharted 3).  The Order 1886 is made by Ready at Dawn and due out next year.  They made Daxter and the 2 GoW games on PSP.  Sony said they have 20 first party exclusives (RaD doesn't count as they're not a first party studio) with 12 new IP in the first year so it's gonna get a lot more than Infamous and Killzone.  For comparison's sake Xbox said 15 first party exclusives and 8 new IP at their conference.

Is there BC for either of the consoles?

No.  Crossbuy is in effect for some PSN most notably Flower and Sound Shapes.

What are the controller changes like? (I really did not like the original PS controllers when compared with Xbox controllers)

Bigger grips to be more comfy for those who called DS3 too small, curved out triggers, concave sticks, dpad improved, latency reduced with digital buttons, weightier.  Also no batteries just like DS3 but unlike Xone's controller.

Is the PSN shaped for the better in terms of community - do you get a headset as a standard bundle?

Headset comes with PS4.  You can connect easily with your friends on PSN I already do on PS3.

Thoughts on titanfall eventually making it to PS4?

probably not though Titanfall 2 should come out in a couple years and EA owns the IP so...
