Well Bose has been around for a long long time and are not influenced by outsiders. Same for Macintosh and SF. They are all old players and know what they are doing.
Imagine the 'McIntosh Labs RS150' getting the Bose design flair,marketing and DSP. That is a Win Win for both. To add to that, if the drivers from SF come into the systems, that's a whole ecosystem complete right there.
So to even think that these three are going to kill any of them, is at this point being naive in my opinion. I am just waiting for these brands to show up and the Bose showrooms ASAP. The timing could not be better as I am out hunting for new speakers. Drooling over the thought of an Active Pair of speakers with McIntosh amp+VU meters, SF drivers+crossover, Bose design+warranty+support. Did I mention auditioning/listening to them while the wife is busy shopping..... Heaven.
