I have the same concerns, but also realize that for every watch collector who thinks that a particular company is moving too fast, there are probably an equal number who would think they were "stagnant" if they did not move this fast.
I am clearly torn on this issue, and for me I think it depends on how much I like the new designs compared to the old. I can't help that bias from coming into play. I personally would rather see more truly new designs, than "upsizing" or adding diamonds or other "bling" to existing designs.
As an aside, I feel JLC is moving faster than GO is in terms of moving away from it's "brand DNA." Although I have bought one of the newer designed JLC's, I miss the days of the older Master series......
