Looking at the Pi forum and also from personal experience, it looks like Farnell have just released another set of mails with shipping dates, ranging from early May (W/C 7th in my case) to W/C 28th May, so if you haven't received an e-mail yet, it may be worth checking your spam/ junk mail folder.
Pleased as I only got a mail last weekend, stating a W/c 4th June shipping date...but as ever, I'll wait until it is in my hand until I believe it :-)

Norway is not that far away, so if it was actually shipped today, then I would expect you to receive it tomorrow.
Otherwise it will probably be Monday, as I would have thought that UPS count Saturday as a 'standard' delivery day.
Actually I have just remembered that Monday is a Bank Holiday' over here, so if your Pi doesn't arrive, then I just hope it isn't one with you also.
Fingers crossed for you anyway! 
From what other recipients are saying it looks as if they are indeed being sent by Royal Mail... but using 2nd Class post, which almost certainly means that they won't arrive the next day.
Hopefully you will be lucky and receive it on Saturday though... fingers crossed!
Oops sorry... I have just read that you had it sent to your office... what a pain! 
Well, maybe if I'm feeling particularly enthusiastic I'll pop in tomorrow morning and find out if anybody comes in to sort the post on a Saturday 
Failing that, well, never mind -- worse things happen at sea!
