Eh, we might hit $900,000. I don't think $1,000,000 is feasible, though I would be delighted if it happened. All the big rewards are taken, Rich probably won't offer any new rewards, so few people have a reason to increase their pledge (apart from the possible patch). Early estimates placed the total at $900,000 and change, and those seem to be on the money.

To reach $1,000,000, there needs to be $150,000 donated within the next three days. That doesn't seem very likely, since that would be on par with the highest rate of gain seen during this fundraiser (around day 8 or 9).
