Like I said, it's a love it/hate it game. Rare took a gamble with this one, and it didn't work out so well.
You have to remember though, this is only the sales figures for the USA, it probably did better in other regions. It broke in about 2% of the market. Rare definitely had to of made some good money off of it regardless.
I can either see Rare continuing to push Banjo because of Tooie's release on XBLA soon, and the next one will be either a merge of platforming and vehicles or a return to roots. If they made another vehicle based game it would be an incredibly stupid move at this point. The game made itself obvious that it was merely an experiment anyway.
