With some price drops and good software it has a chance. It also depends on that when will Sony kill its sales with successor. For GBA's defense I must say that it had pretty short lifespan. It was released 2001 and DS was released at the end of 2004. Actually when you think about it GBA sold pretty huge numbers considering its short lifespan. I wonder why Nintendo killed it so fast with DS. Probably to counter PSP.

GBA was already almost dead at this point, and selling basically NOTHING in JP/EU.  It actually only had 3.5 years on market before it's successor (DS) hit.

No, it just looks like it is dying slowly, except in Japan.

Let me see. GBA shipped 80m and some, and PSP shipments should be around 59m by now. It would have a chance on outselling it if the PSP-Go was a success and the PSP-2 weren't coming this year or the beginning of the next.

With another price cut and keep up the software / pirating yeah it can. But may take a long time.

Depends on when the successor hits.
