I haven't been able to spot the bead in real life either. The little store near my house which carries Pandora hasn't had it whenever I've stopped by.
I now order any Pandora from their Mall of America store (www.pandoramoa.com). They have everything, there's no shipping or sales tax, and you know it's not counterfeit since it's coming straight from Pandora. Their shipping is really fast too.
I ended up skipping the Pandora cherry blossom murano and bought several cherry blossom-like lampwork beads from this Etsy seller: http://www.etsy.com/shop/ikuyoglassart?ref=shop_name_search_sugg
Here is one of the beads I bought:

The photo makes it look far more garish than it actually is. The colors are subtle and the core is silver. It's quite a bit larger than the Pandora muranos. But quite striking on my bracelet.
Than you! Great to know! I will order from them for now on
