That´s for sure, and I doubt we´d see an "alternate franchise" while they´re making the movies which I doubt will ever take period piece route. If they would do a as-it-was-written-Bond television movie series of it might would cost a lot, no question about it, perhaps more than War And Remembrance for instance.Bond is a brand name now: people expect certain things of 'James Bond' including spectacle.
If there will be a period piece Bond, I´d be willing to bet that it'd come in form of a television movie.
