There is also now a V14 model (SCPH-75001) which contains an integrated EE and GS (disputed - see talk page) , and different ASICs compared to previous revisions, some chips having a copyright date of 2005 compared to 2000,2001 for earlier models.
The machine's future continues to be uncertain, with North American and European launches considered to be distant if at all.
V10 and V11 have minor changes.

Many analysts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
Only a few million users had obtained consoles by the end of 2000 due to manufacturing delays.
Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions.
The PlayStation 2 had a difficult start.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
