Yes, Forest City Ratner partnering with Rapfogel's Met Council on Seward Park bid, as predicted

I wrote 2/22/13, Behind that Barclays Center cantorial concert, a whiff of Lower East Side development politics (Ratner + Met Council/Silver = Seward Park edge?):

It's notable that this first Barclays Center event with a charitable focus, will benefit the Met Council rather than an organization in Central Brooklyn, the base for the groups--reflecting mostly black constituencies--that signed the controversial Community Benefits Agreement regarding Atlantic Yards. As part of that agreement, Forest City agreed to hold ten events at the arena, with proceeds going to charity.
Forest City might even wind up partnering with the Met Council on the Seward Park project...

I was right.

From the Wall Street Journal today, Developers Set to Bid on Seward Park:

Some of the city's most high-profile developers are expected to submit bids Monday for the 6-acre Seward Park site on the Lower East Side. Big names interested in the site include Barclays Center developer Bruce Ratner; Related Cos., the developer of the Hudson Yards on Manhattan's West Side; Taconic Investment Partners, which redeveloped and sold 111 Eighth Ave. to Google; and AvalonBay Communities Inc., one of the country's largest developers of rental housing, according to people familiar with the matter.
The prize is a 1.65 million-square-foot project, approved by the city last year, that would be a combination of market rate housing, affordable housing, retail and office space.
...Atlantic Yards developer Forest City Ratner Cos. is planning to bid along with Metropolitan Council on Jewish Poverty, a nonprofit developer of affordable and senior housing with roots for several decades on the Lower East Side.
