Besides being an Nintendo fan, I'm glad to see what was once the last place system suddenly burst to the top. Never before have three systems been in such a tight race. The closest race before this generation of consoles was the Saturn, N64, and PSOne, and that was Saturn getting wipped and Nintendo losing its empire.

Here we have a very dynamic market, and it's all good news for us. Price cuts have been rampant, and surely competition can only encourage increases in product quality.
