The answer is quite simple really.
For those that want Reggie to win the bet it's NSMB vs MW2 on a non-specified single platform in WW sales, which, let's face it, he must mean PC (note he said platform not console) because no doubt according to the people who want this one to be the bet he only has the balls to make such a bet on terms which are the easiest to beat. Obviously Reggie was pussying out by wanting to have until the end of January because NSMB has already well surpassed PC sales, and even PS3 sales. If he wanted to be a real man he would have said by the end of December for this. Any competition on a worldwide basis vs a single platform version of MW2 was pre-destined to end in NSMB's favour by the end of 2009 because of the >20:1 sales differential in Japan.
For those who want Reggie to lose the bet it's NSMB vs MW2 on 360 in USA only. That is the hardest interpretation of the bet for Reggie to win so of course those who want him to lose will insist that this is the only valid interpretation. It has about 1.1 million to make up and about 5 weeks to do it. So needs a lead of just over 200K per week until the end of January. That is a tall order for NSMB because it isn't quite doing that right now. However NSMB could well carry better much legs through January than MW2 so it's still an open contest. If this is the bet you are looking at.
Personally I think Reggie would have the balls to take on the hardest of the possible single platform bets. However he gave himself plenty of wriggle room so maybe he isn't as ballsy as I'd like to think.
