PSP sales 'solid, not spectacular'

One week after the PSP was launched in the United States, American Technology Research found that only 50 of 150 stores surveyed nationally in the last two days were sold out. Another 15 stores had three or fewer units left.

Analyst P.J. McNealy said gaming retailers (such as GameStop and EB Games) have already sold through two waves of hardware, but "big-box" retailers like Target and Wal-Mart got more units than expected and still have inventory remaining.

"The PlayStation Portable (PSP) has been solid but not spectacular. We believe that the PSP launch, while not the blow-out event expected, will be considered successful as retailers continue to sell through existing inventory levels," McNealy said in a note.
