its still very clear that major price movements are initiated on Gox and other exchanges follow along. never the other way around. looking at Gox is still valid, imo.
there is no one price for a bitcoin and there likely never will be. the price you are able to and choose to pay for 1 bitcoin is heavily dependent on local circumstances/economy.
for ex, this is clear with the exchanges. Currently, you effectively cannot deposit or withdraw fiat to Mt Gox and subsequently, the price per bitcoin is worth less USD there than bitstamp or btc-e where you can withdraw. its fair to assume that if people are buying on Gox to sell on other exchanges (say bitstamp), then generally, Gox price would be inflated and other exchanges (bitstamp) would be depressed.
another ex i've seen is in Argentina on localbitcoins where the price of 1 bitcoin is ~$100 USD cash or 900 pesos, which the equivalent of $160 USD. so 1 bitcoin is valued much more in USD cash than pesos. local circumstances have a huge impact on this market, just like Gox.
Places like coinbase and bitpay will use functions like:
1) look at top 3 exchanges by trade volume, take average of the closest two prices
or
2) look at top 2-3 exchanges by trade volume, take average of top 2
