I don't think you understand the concept of a tie. If basketball team #1 scores 100 points while basketball team #2 scores 99 points, that's not a tie. That means team #1 wins.
Do you have a source for your claim? Everywhere I've found it says units sold.
Every unti manufactured has been sold. That's kinda the point. The only GBAs left are in someone's home, broken, or second hand in a store.
PSPs are still being manufactured and sold.
