I don't see the point of releasing this particular model in this tiny, low resolution mini film.
The market demand will show soon whether your opinion is a wide spread one, or the opinion of a small minority.
In the first case Fujifilm will sell lots of it (like all their other models so far, which are selling in the millions p.a. range; instax cameras are more popular than all current digital camera types).
In the second case, when demand is too low, they will not keep it in their camera programme in the mid or long term.
We will see.
I have just given the neutral info here (without any own opinion) for those who might be generally interested in instant film photography. Not more.
But concerning your opinion that instax film is "low resolution" I have to completely disagree. Because of my tests of this material. The film itself has a resolution of 10-12 Lp/mm, which is quite a lot for an instant film. And this resolution is only a bit less than FP100c.
You see the real potential of instax immediately when you use it in combination with a good lens. For example with the Zinstax instax square back for the Mamiya RZ 67 II. You will be really astonished how sharp and detailed the results will be. You will get high quality results, promised.
The problem with instax are mainly the lenses in the instax cameras: Two element achromats with zone focussing. And with that design you simply cannot fully use / exploit the great potential and quality of the instax film.
I am also using an instax Wide 210 and instax square SQ6. Sometimes I get quite good and sharp results, but sometimes I get less. The lenses have in their zones "sweet spots", and when your object distance is the same as this "sweet spot" distance in the selected focus zone, the results will be quite good. But this match cannot always be achieved.
For years now I am explaining to the local Fujifilm representatives here that there is a huge market potential for better / higher grade instax cameras for enthusiast and professional photographers (instant film photography is great at weddings, I have used it there with huge success).
And my local Fujifilm guys completely agree. They see it and completely understand it.
The problem is that so far the responsible Fujifilm managers in the Japanese headquarter are ignoring this attractive market segment.
Probably they are a bit spoiled by the huge success of the current instax cameras in the snap-shooter and mass market (in their 2018/19 fiscal year they sold more than 10 million (!!) instax cameras).
But after 15 years of permanent growth this market is beginning to show market saturation tendencies. And it would be wise to look for compensation by exploring further attractive market segments.
