Look at that chart. Both the bid and ask amounts are declining. But then you notice that a "tick" down for bids is drawn in such a way that it is much more than a "tick" down for the asks. Yet, the price is going up. The only logical conclusion that can be drawn from this is that people are slowly realizing that being in the Gox orderbook (which is public knowledge and reported as market depth) is an inherent disadvantage, and thus while the bid and ask sums are declining the trades are still being executed through market orders or very-close-to-market-orders.
IMO that only means that both fiat and coins are saying "bye bye" to MtGox, slowly but steadily.
