Oh sure, they'll take profits while they can, but the supply increase will start pulling the market down. It's how price signals work.
Only way to keep prices this high would be a multinational cartel of RAM makers agreeing never to compete on price. One defector kills it.

China's not going to want to help keep Taiwan, Japan, Germany, or the USA in the money.
