I´m afraid that won´t change in either franchise in the near future.
The basic themes of "trust" and "going rogue since the former good guys-organizations are already infiltrated by the bad guys" are reflecting on contemporary doubts regarding politics and big conglomerates.
I agree with you that this does not feel particularly fresh or exciting anymore - one does not expect anything else from governments, sadly - and to have the new "Mission Impossible"-movie rehash that kind of plot is disappointing to me as well.
However, the "Mission"-pictures, at least IMO, are mostly excuses for over-the-top action sequences, with lots of "wink, wink, we´re only big time entertainment". None of the previous four films even remotely attempted to be anything but pulp fiction, and therefore I do not see or enjoy them for their plots, only for their level of "we dare to go even further".
I also agree that the trailers for the new film do seem to copy the style of the last film - no wonder, since that was mega successful. But even if the hanging on to an airplane in full flight has already been done in OCTOPUSSY - I can´t help but grin with fond anticipation when I see that bit of the trailer.
So, yes, I will want to see this film.
Regarding Bond - well, with the organization of "Spectre" probably having people everywhere, too, the film will have to deal with Mi6 uncovering that conspiracy. I don´t think that the story will repeat the QOS-idea, however, of Bond really going rogue. It will perhaps be more of "Bond, M and Moneypenny" fighting secretly against the enemies within their organization. At some point, this kind of plot will not be repeated in future movies. For now, it is an integral part of the Craig era.
