It was confirmed that they recieved another huge team to help with the development of X and Y.
I'm not an expert on game developing, but you usually don't focus on one project. Gamefreak has been most likely working on it since 2010 as a side project, and after BW was released it gave they enough time to focus on it and put aside one small team for the development of BW2.
