Will the scale Lionel Berkshires have sounds specific to each roadname, including the PE version?

I read the 2014 Signature Catalog and Christmas catalog descriptions and couldn't find any information. Has Lionel announced whether the scale Berks will have the prototype whistles for the NPR and Pere Merquette Berks? What about the Polar Express Berk - is it correct the movie version used the Pere Merquette's whistle and engine sounds? If so, then it'd be correct for Lionel to use that whistle for the PE version. And, has there been any announcement on whether the scale PE Berk will have movie sound clips? There was nothing in the catalogs about that either.
