There is an essential difference between engineers evaluating engine configurations in the cold hard light of winning on the track and in the showrooms versus fans, devotees, and mechanics (no matter how competent or with what qualifications) "liking" or preferring a particular engine type. Unless the engine configuration is a brand identifier, such as Ducati and HD, the engineer will pick the best compromise to achieve the highest priority such as packaging, handling, power, type of power, cost, some of which might be complimentary or at the cost of another quality.
If the engine configuration is part of the identity of the brand then the compromises are dictated by that fact. Just look at Ducati as an example. Of course I state the obvious but it appears that is exactly what BMW did and has been successful. I think they will do the same with their 600 if it is in fact being built. It would appear that MV is going the other way as did Triumph. Both have a history of triples and are using that aspect of their brand to market the middle weight bike. Note that MV went with an in line four with the F4 having a long history with the inline engine.
Honda, no matter what fans of the brand want, are not identifying themselves as a "V4" company. They bring to market what they think is best.
