Yep - I have a friend who takes pictures of (very expensive, high profile) weddings all around the world with a MF film Hasselblad. They still can't be beat
Hasselblad is like Montblanc of fountain pens, or Glock for handguns, at the end of the day, there is a leader in any field and they get exponentially high attention (because everyone can name that one leading brand name in any field), so they just charge that much more.
At the end of the day Hasselblad is only 6x6 (i.e the negative size), but there are many bigger format (in medium format) cameras available like Mamiya 6, Mamiya 7, GW690III (which is 6x9, twice the negative size of Hasselblad H1's 6x4.5).
Hasselblad is nice, and fortunately not that expensive these days (probably Leica gears are still costlier :p )
If you are looking for the ultimate medium format system camera, the obvious answer is Fuji GX680. It's waay bigger than the Hassy, and you can also put digital backs on it. The only downside is it's electronic camera, not mechanical.
