Release Date for X5 Box

As the subject line says, im just wondering what the shipping dates are like for the boxed version. I have ordered the upgrade version from Amazon UK and an estimated dispatch date of the 15th March is listed on my order confirmation. Obviously, ive seen elsewhere dates such as 27th mentioned.

I am currently using (aside from my old trusty X4 ;)  ) the trial version which now has 20 days left on it.

Enjoying working my way through it and have just had a play with the mesh tool... superb improvements in that area guys! - WELL impressed. X5 really does feel like a far more polished product than X4.
