I got an e-mail telling me that I only had 2 days left to upgrade. That was 3 days ago. If I try and download just now though it still lets me. I wouldn't keep my hopes up for 2 weeks though as its probably just waiting on someone taking the link of the site and they have either forgot or are on holiday over the festive period.

Edit - Received another e-mail today saying this is the last day.
