They do not have costs to "amortize" but they do have licensing fees to pay to Toshiba for every unit made I imagine. It is a case of "6 of one, half dozen of another" I think here. Now Toshiba could be thinking; "we already paid the R&D price, so we can lower the licensing to recover that R&D over a longer period to help promote the format", but that is pure speculation.
I really like the "Hollywood marriages of convenience" & "they won't think twice about "cheating" on Sony" remarks. Doesn't that describe follywood to a tee? Even down to their commitments to REAL marriages.
