Firstly, what is meant by too chocolaty or too vanilla?
Secondly, my first post made me look like an idiot. So, to clear some things up,
From my understanding, the resources in minecraft ARE limited. There's only so much of it. Glowstone is extremely limited. Some resources are readily available. But still, it takes time and effort to mine something as simple as dirt. Even dirt is limited, or water, or cobble, or wood. We don't get things out of thin air. We have to find and mine them, right? If everything was unlimited, there wouldn't be a price tag. Everything would be free. There would be no buyers and no sellers.
From what I learned in my high school economics class, the price is determined by the intersection of the supply and demand curves. If demand increases, the entire demand curve shifts to the right. The buyers will pay more for the same quantity. If supply increase, the entire supply curve shifts to the right. The seller can provide more quantity at the same price. This usually means that costs have gone down for the supplier. What's going to happen in this nether wipe is there will be a sort-of surplus in glowstone - a supply increase. Since there's going to be so much of it, wouldn't price decrease? In response to a supply shift, quantity demand will increase. The demand curve won't shift. The equilibrium price and quantity will just change.
In this next major update, there will also be a shift in demand though. Glowstone will be used for brewing. Since the buyers know there's plenty of glowstone, they may demand more of it.
Most of Apple's products have had a falling price over the years despite inflation. I think this is because Apple's costs have gone down.

I'm only a senior in high school. Maybe I don't understand it completely. Please enlighten me if I'm wrong.
Thirdly, I'm looking forward to a larger map. It'd be nice to have an infinite map, but I can't even comprehend how that would affect the lag.
