The only real issue i have with moving from 35mm and/or Digi is the expense. It is rather expensive to buy a quality device, as well as all the film you will need to produce shots.
One of the main reasons i moved into the digi relm was the learning factor. with a digi and a multi-gig card, you can experiment without worry.
I think my main advice, would be to keep the interest alive for medium format, but realistically move forward with it once youve mastered your eye. Medium format cameras are great for the experienced, and fun to use on an occasional basis. If you are willing to pay the price (literally) then go for it, to tool around with when you have some extra cash to buy all the film.
Either way, it would be a fun experience and give you the ability to stray a bit from the routine of digi.
Enjoy!
