I don't think the camera I will buy be obsolete by any means, don't worry about that.
The main reason I ask this is because the D7100, while it is an AMAZING camera, the night shooting actually seems to be a step down compared to the D7000, while it's daytime shooting is a step up. Because of this I know that I may not feel 100% satisfied buying this camera, knowing that the nighttime shooting is actually worse than what it's supposed to improve on. I love nature, both during the daytime and nighttime so both day and night shooting are equally important for me. However, the cameras that are an improvement over the D7100 and I know will satisfy both my needs are in the full frame range, which basically almost double the price (at least in my area) and are way out of my pricerange.
I am worried that if a new camera releases, in a worst case scenario it will solve my slight worry about the low light image quality (especially the banding it seems to have, which is less prevalent on the D7000 according to some people who own both) making me actually have serious regrets about my purchase, or in a "best" case scenario, the price of the D7100 price will lower quite a bit shortly AFTER I bought it.
Normally I wouldn't mind this as much, but as a university student both of these situations would be a pretty big blow. I still remember that the pricedrop of 500 to 300 euros of the point and shoot I bought a few years back felt like a kick in the groin, especially since I don't have a steady income.
The reason for this question was mostly because I am unsure if I should buy the camera soon and get more practice with it, or wait as long as possible before my trip to Scotland in september (which is the main reason I want it this year) and see if a better camera would come along, or at least a pricedrop because of a newer model that isn't really an improvement.
I know that with some products the "Big guns" in the industry have releases each year around a specific month, like for example right after a convention dedicated to the product (sort of like what is going on now) and I hoped that this was the case for cameras, so I could have a more "educated" guess of how long it would be for a newer and possibly better version of the D7100 to come out.
I do appreciate all the advices though!
