I too had preordered mine in Febuary, and my account page said it has been shipped on April, 30. A person in #openplug on freenode mentioned that they had ordered their guruplug in april and got it in april. I immediately emailed GlobalScale, and a shipping notification with a tracking number magically appeared in my inbox mere hours later.
Its beginning to be more than a trend, I guess. I'm just glad to e getting my guruplug, and that I havent had any hassle with GlobalScale yet. Next time I however will most likely order from NewIT.
