The site is incorrect at that point, if you look here

shipping times for the EU are "normal" (which in my case was 3 days, should be the same to Italy). The link was given to me by chessnutech chat support and updates weekly.
Granted I ordered a Go but I had the exact same "preorder" and "3 months" on my product yet they delivered in 3 days because the information on the product page simply isn't true, what matters is their shipping update.
Thanks for your comments... while portability is at the top, I'm still tempted by something better looking like the Air, for example.
Beside that, shipping time for the go seems to be incredibly long... on the official wesite I can "pre-oder" (why pre-order? Iunderstood the product has already came out) and estimate delivery to Italy is in approximately 3 months... I'm pretty confused
