Later, Sony gained steam with new development kits for game developers and more PlayStations for consumers.
Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions.
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).
Later hardware revisions had better compatibility with PlayStation games (Metal Gear Solid: VR Missons works on most silver models).
With a price of $299.99 per console, Sony made gross sales of roughly $153,000,000.
There are also some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000.
Two propositions were to name the old model (EE and GS, separate chips) V11.5 and the newer model V12, and to name the old model V12 and the newer model V13.
