As some of you may or may not know, Vodafone stocked the Xperia X10 for about 2 days, and then it was removed for purchase on their site. I sent them an email not long after it happened, and only just got the response:
Thank you for your email.
I’m not able to tell you when the X10 will become available as we haven’t been advised.

So there you have it, even Vodafone don’t know when they’ll get it back. They also didn’t have a reason as to why it was removed for purchase in the first place.. weird..
