Never believe everything you read. I always check Takara Tomy Mall (http://takaratomymall.jp/shop/c/cPlarail/ ) and 1999.co.jp and none of them list it. Besides, a brake van included sounds boring anyway, and it's definitely not going to be T-21.
Tomy just released Harold in the Tomica line a few days ago. That's the most recent product we know about at all, besides the next Capsule Plarail wave with Ryan, Skiff, and Henrietta with a face. Last year we found out about quite a few new Thomas products in late January, and almost nothing has been promoted for the Japan release of Sodor's Legend of the Lost Treasure, so there's still time.
