A:AnswerMSI has yet to release this model to retailers. Best Buy labels it as "Sold Out" as a way for them to inventory their online store front for when the product is actually released. The best timeline for release that I've seen so far is late March, March 31st as labeled by Amazon.
A:AnswerBest Buy offering preorders is very spotty. If you want to preorder, I'd suggest you go to another site like Amazon or B&H. The best timeline for a release date for this product is late March, March 31st listed by amazon.
