Yeah I think that's correct. I've been told by vodafone as above that nokia are holding back for some form of update. My suspiscion is that they're awaiting Cortana avaialbility for the UK/Europe (but that's just conjecture on my part)
It makes sense to have everything 100% before releasing, it's just nice to be told that's the reason why rather than guessing what's going on. A few of the more impatient of us will be cancelling orders/losing interest left and right, which is a shame IMO as a lot could be avoided with a couple of decent press releases. It seems odd that there's zero pre-order option at the moment (on contract I mean) for what is meant to be a flagship device.
Maybe providers don't think WP is as important as Samsung and Apple?
