Not sure there is any beans to spill, they are out. RCLipos has them in stock:

I've got these two with this slick little charger called the Nanophosphate Mini.

I just got them a few days ago and I'll be testing them out this weekend. I'll post up more news once I've run them. About the only initial comments I'd make are that I can't believe how light they are (185g) and that you can charge them in 20 mins (albeit at 8amps...) we shall see...
