This news comes from Samsung centric site - SamFirmware, who also says that Samsung will stop supporting Windows Phone by the end of 2012, and will likely release only one more Windows Phone 7 device before dropping the platform all together.
While Samsung has still to confirm this news, we know that Samsung has been working hard to build up it's own offering in BADA. We are not sure if they try Apple's approach on delivering a hardware and software solution from their own ranks or continue providing their users with a variety of offerings.
