Are we sure this is supposed to be the late 23rd century London skyline? I know people say they see the London Wheel near Cumberbatch in the poster but even if that's the current Wheel by the Thames I have to wonder how many major cities survived the Third World War. Riker in First Contact
said most of the world's major cities were destroyed yet San Francisco...Paris...London...they all seem to be intact and you'd think all three would be major targets in a worldwide nuclear bombardment.
Oh well, if it really is London that'd be kind of cool. It'd be a nice change of pace from almost every significant Earth event in Trek films happening in or near San Francisco and within eyeshot of Starfleet Headquarters.
