Another new LEGO City 2012 set has been revealed courtesy of Smashing Bricks. There are 403 pieces and 3 minifigures included in 4205 Off-Road Command Center. Looks kinds similar to 4643 Power Transporter, but I think this will sell a lot better considering its police theme based. As for pricing, you can expect it to be around $49.99 -$59.99 USD.
