.info might be having a low moment now(which also means a good time to jump in as an investor) but it is not dead. Its still a gTLD. Supply of top quality names is still very low.
Also, why would someone buy pizza.info at $20k+ and intend to resell it? makes no sense to me. Domain investors need to be realistic- there are some prices that you buy a name for that you cant make even 100% profit off that name because the price is too high.
