Limited to 2000 units
No release date yet, but i suspect it'll be another Toy Show Exclusive.

It's happening! TakaraTomyMall has just revealed a Masterpiece figure that will surely send fans into a frenzy: MP-18B Bluestreak! That's right, it's a blue Bluestreak! This deco is based on the Diaclone figure and has been a color scheme desperately wanted by the fanbase.

According to the web page, it looks like this will be a limited release of about 2,000 and available in Japan, likely as a web or other type of exclusive, so it may be one of the more difficult pieces to obtain.
