No. Around 98000 copies (which was barely enough for Ion to break even on).
98000 copies!!!!! Of the best fucking game EVER MADE!!!
I've never heard those figures before ... but certainly for a game that won 35 GOTY awards (!) it did not sell well.
And now Looking Glass and Ion Storm are gone (admittedly Ion made mistakes with DX2, but imagine if they had a chance to learn from those). Irrational Games is maybe our best hope right now. Bioshock needs to sell. Like Ken Levine said when announcing it, emergence is the future.
But developers don't make those kind of games because, as well as not selling, they are difficult to make. It's hard for developers to make a game that caters for player freedom and experimentation, and also have strong narratives, like SS, DX and Thief do (this is why DX2 was an interesting experiment, but let's not get into that now :)). Much easier to make a totally linear shooter where the developers tightly control every occurance. Easier for them, unsatisfying for us.
