they need to make some instax (wide) b&w film! and while the last design of the instax camera looked like globular leftovers from a sperm bank, I think the whole new 'vintage' thing is really gimmicky and in my opinion, a little tacky. but that's just my opinion and doesn't seem to agree with the rest of popculture today that insists that everything must look 'vintage'
If they want 'vintage' it would have to have full manual control of exposure. Even if it only has a 3 element f8 lens give us user selectable shutter speeds and aperture control. That with the instax wide format would be true retro and you could actually sell some to people who care.
