The 121 Overlander contract has seen interest from a number of Companies, including Armor Holdings (AT/S&S representative) who are submitting the Pinzgauer and various models of the S&S truck range.
Many of the competiting companies are displaying their "offerings" at the current Avalon Air Show in Melbourne.

Armor had a 6X6 OAV (or WP as they are now calling it) on display:


On a personal note, whilst I understand the bulk of the vehicle is basically as previous models I personally think the new front design is TERRIBLE!
I realise I'm probably going to get some flak over this but....
.... If a Designer came up with that concept then they should go back to College where they got there degree and ask for their money back ....OR.... MAYBE the company should employ a designer rather than get the janitor to do the design work.
Fortunately I believe the "front" is a prototype only, so maybe AT / S&S / Armor will come to their senses and design a front applicable, and in keeping with what the vehicle deserves.
