Bought my 350 around Oct/Nov time. Registered and got my discs within 2 weeks.
My folks got their 350 earlier than me, but like most things A/V, waited for me to go round and set it all up for them, so it didn't get up and running until late Nov/Dec. They had trouble registering and didn't manage to get their discs, but as the deal price for their 350 was £50, they're not complaining too much.
