HP Prime Graphing Wireless Calculator

[R_Gtx]

Contemplating the purchase of a HP Prime Calculator, I checked the HP site (UK) to see the current state of play, and find that there are two variants listed:
HP Prime Graphing Calculator (G8X92AA)
HP Prime Graphing Wireless Calculator (G8X92A6)

only the former is priced, and on HPs US site only the latter is listed.
So, I came to this site to find the differences, but a search of these forums draws a blank.

My question is; is this a newly released variant? The calculator specification makes no mention of wireless connectivity, yet the name "Graphing Wireless Calculator" suggests that this is a prominent feature.
