So far, only in Curry's:

The specs for FP-Ready models list the tuner as "Freeview Play" instead of "Freeview HD". Which seems a bit of an anomaly, given that FP is all about streaming. Panasonic's website labels them as "Freeview Play Inside" (http://www.panasonic.com/uk/consumer/viera-televisions/led.html)
The a516digital site says:
Freeview has advised purchasers of these devices that once Freeview Play becomes available, the TV will alert users that an upgrade is available - but the TV needs to be connected to the internet. The upgrade will update the TV's software so that the Freeview Play service becomes available from the TV guide. A new Freeview Play home page will become available.
