Oh, you did indeed!
I ended up noting your note about Wii Fit possibly being knocked out of the top 10. That actually seems possible. Wii Sports Resort and New Super Mario Bros. Wii passing it are obvious ones, but I'm not sure what else might. Black Ops and Wii Fit Plus might be the only contenders.
I think the top 10 for the generation is quite set by now. Which is 5th and which is 7th isn't that obvious, but there are only around 12 games or so that realistically can make it. Wii Sports obviously takes the top spot, then 2nd to 4th spot could be New Super Mario Bros. Wii, Wii Sports Resort or Wii Play. Then we're most likely going to see Mario Kart Wii, but there's still a bit of a chance that it will beat Wii Sports Resort or New Super Mario Bros. Wii. Which is really quite interesting, I'd say the top 5 is very likely to be all Wii. And all 30 million plus.
Then New Super Mario Bros. DS seems a pretty obvious 6th place, with 28 million or something.
Then either Wii Fit, Wii Fit Plus or Black Ops I'd personally say Black Ops > Wii Fit > Wii Fit Plus seems the most likely, but I'm not really sure.
Then Mario Kart DS, and then Modern Warfare 2 just in front of Brain Training, which will be the 11th best selling game of the generation, and the last one to sell 20 million.
There's really nothing else upcoming that I see having a chance of getting up into the 20 million range. Other than the 3DS games, but they're disqualified for being 8th generation games.
Edit:
Oh! Pokemon Black and White could stand a chance, I suppose. It's looking at 5 million in Japan alone, quite a bit higher than Diamond/Pearl which saw only 3.5 million.
Pokemon games sell for a long while. I think Black and White is going to be marketed as a game to buy with your 3DS, even though it's a DS game. I don't think there's going to be another Pokemon game for a while, as Heart Gold/Soul Silver was recently released too. I'd say Black and White is likely to be the last major selling DS game, and it stands every chance of making 20 million.
