This stuff will not be on Amazon except the LE. And Amazon Marketplace does not support Amazon Prime (except if the product is fulfilled by Amazon) The poster probably does not have an item order, nor the "Launch Event" shirts, or even the pins which were limited to begin with.
This stuff will probably be on eBay, though, like the KH3D launch stuff was.
I'm SOOOOOOO snatching that poster off eBay whenever it appears. The pin I can live without. From the look of the picture, it's just the logo right? Can't really tell what the other stuff is, but I'm sure there's WAY more stuff that'll be there than what's in that picture.
I like to go all the way when shopping for stuff. I coulda got Okami Zenkkaiban for $19.99 on the PSN, but I want a physical copy. I trust myself more than a piece of hardware. The real deal is $43.99 on Amazon. Ouch. WORTH EVERY PENNY!
So KH stuff? Yeah, I'll lay on the dough for good quality merchandise. ESPECIALLY limited edition/special edition ANYTHING! >:3
I bought Okami on PSN, realized that my OCD will never ever ever accept digital items instead of physical items, and then bought a like-new copy of Okami HD on eBay.
