image quality looks the same as from all digital canon's I ever owned starting from my Canon 10d.
These samples don't say anything about improvement in image quality to me. But we are buying them for comfort and speed nowadays...
The only thing to hope for in the future is that the dynamic range will improve drastically and I still prefer the look of film. Digital photography has improved insignificantly in the past 10 years and still has a long way to go.
Perhaps an entire sensor re-design is long-time due instead of chasing more pixel counts.
