Will Layla Stone be on Amazon US eventually?

My understanding is that she is a Walmart exclusive, but these dolls aren't sold in the country where I live and the easiest way for me to get them is Amazon US. So my hope is that after the initial drop she will eventually show up there for the normal price, right? How long does that normally take?

I originally only planned on buying Claire, Carina, and Willow. I just received Claire and Willow today, and it made me want to collect all of them :3
