There is always a new printer [camera/computer/tablet] coming out soon. It's going to be [incrementally/significantly] better than the current model. But if the current model meets your needs, it will still meet your needs when the new model comes out.
I'm still happy with my 3800, my 5D Mark II, my first-gen 27 inch iMac, etc. I think all of them were purchased just before the new model was introduced. (In the case of the 5D, I did exactly as you and waited, and waited, and waited, and finally, knowing the Mark III was coming out, found an excellent price on the Mark II and bought it.)
If you've really been waiting for a year, that's a year that you could have been printing.
