At this point it means nothing.
DS didn't destroy PSP due to its price alone. It destroyed the PSP due to software.
Look at DS' history, it sold about as good as 3DS is now until Nintendogs released followed by Brainage. Once those came out, it was full steam ahead.
3DS now has a far more mass market friendly price. It now needs to forgo the 10 year old ports and focus on compelling new games.
