Boiled down to its essence, we have a repeating theme here: anyone who wants more MP 'doesn't get it' and is basing their desires on a flawed assessment of their needs.
Then we have to discussion of viewing distances. It was used by film Leicaphiles to explain why their outfits were 'as good as 6x7' then and we are hearing the same flawed argument now. The concept of Normal Viewing Distances is not as universally true as some suggest. If it were, producing prints for exhibition would be so much easier and quicker. I'd welcome that.
In response to the comment, 'Since when a camera role and function is solely determined by just one part- the sensor?', who said or implied that? The issue here is that some people would like to see a higher resolution sensor in the X series and for some utterly strange reason, there are those who feel the need to tell them that they are 'wrong'. I completely get why many, perhaps most, people would not desire more than 16MP, but is it really that difficult to understand why some might? Those who would like more MP are also not suggesting that this is the only thing they care about. Nobody said or implied that, but it stands to reason that if 16MP is not considered enough for one's needs, its only logical that a camera that is already categorically 'ruled out' on this basis is not going to be reconsidered because it has other desirable traits.
Nobody is saying the X-T1 is a bad camera. Nobody is saying nasty things about Fuji, or that the cameras you own or aspire to own are not good enough. So why the defensiveness? Its because I believe Fuji could have produced a cracking 24MP sensor that I wish they had, but maybe they just couldn't (or couldn't afford to)? If so, that's a shame, but would not stop me hoping that they can in the future. Not everybody covets impeccable noise performance at 6400 in every camera they own. Besides, the idea would be to compliment the 16MP line up, not replace it, so people could still choose what's right for them.
FWIW, I print at 13x19" for portfolio. All my display prints start at A2 and go up from there. Far from being a freak, I know that many work like me.... and you can still make beautiful small print from high res files when you want to!
