Is This An HSPA+ Nexus 10?

During all the hubbub that was the Google I/O keynote, Google released a promo video showing off its Hangout service.

In that 90 second clip (which features an actor ridiculously holding the Nexus 4 upside down) there is a scene about one minute in of that same actor picking up what looks like to be a Nexus 10 and when it transitions to the device's screen, we're greeted with an HSPA+ icon in the top right corner.

While it should be noted that the clip also features a Nexus 7 with an LED notification light (perhaps next N7?) it could simply be a case of a marketing company that has no idea how their client's (in this case, Google's) devices work.

Or

Google themselves could be trolling us all and teasing upcoming devices.
