II'm From Hungary and I've just bought one yesterday, GL503VS. There is stock her for Hungarian market so I wouldn't say they've pulled it out (we usually got VERY limited stock from asus stuff, so if we got it, and you can't get it that would prob. mean they are out of stock, sold out).
In Hungary the wait for orders now usually 2-3weeks per model. I've bought a PG348Q Monitor recently and I had to wait for my item for almost a month to arrive. This should get better as we stepped out from the holiday season though IMHO.
