Will the GazettE's single Vortex be coming to iTunes?

I was just wondering is the GazettE's new single Vortex will be on iTunes any time soon. I would really like to buy a hard copy, but I'm not sure of what websites to look at, mainly if they are reliable. A friend of mine told me to order it through yesasia.com. I know that it says that the item would be eligible for free international shipping, which would be me, but is it reliable? Normally I get my sister to pick up cd's for me when she comes home to visit, so if anyone could help me that would be wonderful. Thanks!
