Similar to yourself I have been away from photography for a few years and rekindling the hobby, I was a original Q user at the time and have come with the Q2 as my camera of choice.
So simply put if you want a sealed camera this is the one to get, if you want the quality of the lens then a Q will do an amazing job, the major benefit of the Q2 for me is the ability to crop as you have outlined. I have posted a pic on photo of the week which was taken from a fair distance.
So brass tax if you have lots of money get the Q2 if you want to sell a few lenses and put some cash in your pocket get the Q - honestly just get the Q2 and ignore my sensible advice you will love it.
