Film photography is on the rise, as is evidenced by the price of s/h film cameras going up (significantly in the case of some models). Maybe this is just a fad, and things will drop off again in a year or two, but any attempt to bring a new camera to market is a good thing IMO. Without new cameras being produced, eventually working old cameras will become scarcer and ever more expensive, leading to fewer people buying and processing film, and a general decline in the format.
This new camera doesn't have to be the best camera ever made to succeed, and anyone who doesn't like it, or is happy with legacy cameras is under no obligation to back the Kickstarter or buy the finished product. If it turns out to be a bad camera it will fail of it's own accord. But, if it's a good camera (even if not best in class) then it may result in further new cameras being brought into production - ones that are even better, or include features previously unavailable with older technology. This is a good thing. At the very least, it will be the option of a brand-new, supported, in-production camera being available for those who want one.
