I don't think that there's a perfect time for anything. I am of the opinion that there will always be room to create stuff, it's just that for certain categories the preparation time will be longer.
Building an MVP will just take longer. So rather than measure the time to a workable MVP in weeks or months, for a product to stand out as being valuable it would probably take a year or more for users to want to consider making a switch.
In fact, I'm working on something vaguely similar to BW on the side. I don't know if I'll succeed or not but I'm loving the research I've been doing so far.
