Could they offer an add-on viewfinder later?

Not happening.
Personally I think given the price and image quality, I don't see it as a deal breaker. After all many medium format cameras were also of the type of "look at something" though I understand the value of optical vs electronic, but many people who complain about lack of EVF or OVF don't seem to have much problem with EVF's.
Personally to me the potential deal breaker is ergonomics. On first pass to me it seems it has great ergonomics but dpreview made the point that some buttons like the green/red are hard to reach for important functions. If that is the case, then I think Pentax missed with what is one of their core competencies. They should have used the whip on the designer to say "these things need to be close, you make it work design wise."
