Call me crazy, call me a fanboy, call me whatever but I think PS3 has a decent chance of breaking 20 million by next year. If current sales are sustained (~150,000 units/week) along with some boosts along the way from bames like littlebigplanet and resistance 2, going into Christmas it would have to sell a little over 2 million to hit the goal. This is purely guesstimation of sales, though. I think this feat is possible, especially with the introduction of the "new" 80GB sku and a few great games.
What do you think?
