I think the goal is realistic: the Wii crowd will eventually get bored of playing Wii Sports and seek a console with a wider offering of decent games.
Moreover, HDTVs have been selling really well lately and the PS3 is the perfect addition to them.
Even if the hardware sales goal is not met, I wouldn't worry too much: a large part of the income is coming from software licensing and on that front, being the only console to this day that hasn't been hacked is a huge advantage.
