I'm going to pick up an M9.
As far as "New Stuff"- it is not always better. I still write embedded code in Assembly language because it gives the response time that I need. I like older lenses for the look that they give. But Digital Cameras, the march of progress for high-end gear usually means better images.
I've learned the hard way - gear may improve image quality but has no bearing on making better images.
After spending the last year learning how to make prints (silver gelatin fibre and platinum palladium, I've come to the inevitable conclusion that the quality of my gear is more than sufficient to great the quality of prints I aspire to craft...
good luck whatever you decide...
Must agree with quoted comments
Its all a matter of balance I'd say. Maybe I'm a no risk person, I'll stay at the middle balancing opinions. I can't forget to think about the great masters of photography. Think of HCB, he used to use what? One camera 2 lenses, 1? He produced so many great images... We all agree about that. When I have the lust for new gear, I watch the documentary we all know that sits at youtube.
Being open minded, perceptive, compromised with the environment (respectful), concentrated and have a lot of luck are part of he things that make our hobby fun. All of it have been said (magic numbers, contrast, interesting subjects)
Despite it was not named, I think we all pursue these holly grail, make it in new gear, new techniques, new behaviors at taking photos. Maybe its the path we choose or the objective we follow that differentiates us all. Maybe its a journey we all walk differently. Mine is for images that catch the eye, make you think/look twice, beautiful things that make you come back over and over again without boring. The awww factor. I still did not get It, none to my taste must admit, far away from it!
Don't want to say HCB was the holy gray holder, but, he made it simple, did not care if film was lost during its shipping to Paris or if it was bad developed at the location in Bombay, he was there like letting it be, floating in the air. Tools seems were not so important to him, it was more like the leica he was using atm was a nice tool, and he used that to better fit his ways, purposes.
On the other hand, I do also love new gear (and my new to me and until the grave M4), the unknown, unexpected thing I want from it. Is it all what I wanted/expected? Anyway, looking at the great masters work, interviews, writing makes me more humble and calm down my lust for new gear, the GAS thing as I've learnt to call it here.
