What product was secretly unveiled in this armored truck during CES?

Valentin Sama from DSLR Magazine mentioned on his blog that after signing a non-disclosure agreement (NDA) he was invited to this armored truck during CES with some other journalists to see a new “secret” product.

The limo company used was 24-7 Limousines out of Las Vegas. Does anyone know more about this truck and what was inside? Maybe somebody knows who hired it during CES? You can contact me anonymously here.
