Erm no. Thor was released first. In HK. So he will be in stock first.
Your thor may have gotten charged today because you were on waitlist or flexpay but that does not mean he isn't in stock before Cap. Just go with HK releases. Thor releases first hence Thor gets to sideshow first. Simple logic
I know because while my distributor for HT is not sideshow in Asia, I got my Thor first and Cap coming by next week.
Released in Asia yes but to America no. Cap might have left port 1st, been on a faster ship,got unloaded 1st, etc. I was not on flex or WL for either figure. Not a big deal but SS had (or said they had) cap 1st. Not big deal i will get a shipping notice someday.
