In my area (Canary Wharf in London) with Google I can see the Crossrail works going on but there nothing happening on the Nokia maps so Google is more recent here.
Came here to say the same, google maps imagery of my area is about 7-10 years old.
I was convinced the CIA was watching me, because I've been checking Google Maps for over a year now and the same white van's been parked outside my house for all that time. I just saw that on Nokia maps it's left. Thank goodness!
