However, the release of several blockbuster games during the 2001 holiday season pushed the PS2 far in front even as the Xbox and GameCube made their impressive debuts.
As of V4 everything was unified into one board, except the power supply.
Later hardware revisions had better compatibility with PlayStation games (Metal Gear Solid: VR Missons works on most silver models).
Developers also complained that it was difficult to develop for the system, with little in the way of reference material from Sony for its exotic architecture.
There are also some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000.
It was not until late 2001 that the Microsoft Xbox became the second console with (non-standard) USB and DVD support.
To this day, the PS2 holds the record for the most consoles sold in a single day as well as the record for most consoles sold in launch day in America.
Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port.
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).
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PS2 launch seemed unimpressive and gaffe-prone, compared to the well-planned launch of the Sega Dreamcast, which was making a genuine attempt to woo developers and which had better launch titles.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
With a price of $299.99 per console, Sony made gross sales of roughly $153,000,000.
