Purchasing the N4 in the UK

Hey,

So the Play store now says we are able to purchase the phone from the 13th November (Can not wait!!), but how long do you reckon it will take for it to be posted to us?

My university don't take post at the weekends, so if i didn't get it by Thursday it would be highly unlikely I'd be able to open it until the Monday =/

Also, do you reckon the trade in value of the Galaxy Nexus will decrease after the release of the N4 at places like CEX?
