Release date unconfirmed between December 2009 and January 2010, the price shown is 20,000 Yen (exclusive of tax).
No other details regarding this merchandise is available at the moment.
For your information, PSB-Mall was also first to set up the pre-order page for MG Guntank back in mid May, long before any other Japanese site has such info. The price posted for that MG wasn't correct but it was quite close to the confirmation from Bandai some two months later. The release date listed was exact though.
So, the credibility regarding the release date and price is quite high.
