I think those listing are for 2-disc SE's for the most part. White Heat could simply be a single disc release we don't know the details about yet (like how they kept the single disc releases of Grand Hotel or The Great Ziegfeld from being known until the press release).
More Region 2 info, courtesy of davisdvd.com which will likely spill over into Region 1 around the same time. These are the Scorsese films (GoodFellas, After Hours, etc.) and a re-release of Heat. Click here
