Sammie 323's Effluvia has posted scans from Entertainment Weekly's fall preview edition for The Good Shepherd and The Departed (parts one and two). There's also a cariacture of Matt in the Oscar preview section for The Good Shepherd. No mention of Margaret that I could find.
Premiere magazine's fall preview issue is also out, and I have not yet seen the preview for The Good Shepherd, but the one for The Departed doesn't really reference Matt.
Scans from People magazine are below, with thanks to Julie.
