I"m waiting for those as well. Had my chance to get the real ones on ebay for $6000 a few years back and I'm still kicking myself in the ass for not getting them.
There is someone developing them on the Brotherhood of the Bat. He sold one on ebay. Around last thanksgiving I heard his shed burned down in a fire.... he only recently started the regular begins gauntlets, not the ninja gauntlets.
So short answer to your question.. no. I don't think anyone has ever developed them...
ack! you're right... i got celtic touch confused with PatrickJ or something... okay.. perhaps his shed didnt burn down lol:lol
but I did speak with celtic touch and he definitely said that he put his first pull on ebay to get an idea of the market out there... and that was the last I heard from it..
