But I don't know where you got this idea... if ROTJ:R and ESB:R are released at the same time, I will eat a pack of dual-layer blu ray discs. DUAL LAYER.
I had this idea over a year ago when it looked like ESB:R was pretty much done but hadn't been released yet. There were a few comments either here or on FB that ROTJ:R had already been mapped out, it might have been the conversations about the B-Wings playing an extended role in the 2nd Death Star battle that made me ponder the possibility that maybe Ady was pulling a fast one and was gonna do a double release. This was before I knew he was creating models for the matte paintings and still had an extensive list of items on ESB:R to complete.
