I think an excuse for a new bow is great, but what is most important is that you get yourself in top shooting form. You say you have not shot in 10 years, so I think a trip to a quality proshop is in order to help you get back into shooting. I think a new bow properly setup may indeed help you shoot better, todays technology is head and shoulders above anything made 10 years ago. I know your old bow, if in good shape will do the job, but for a once in a lifetime hunt I would want the best I could get my hands on!
