Megadrive1988 said:keep in mind, PlayStation2 came down something like this:
Jan or Feb 1999 - PS2 CPU revealed at IEEE @ 250 Mhz
March 1999 - full Next Generation PlayStation (PS2) specifications unvieled, including Emotion Engine, Graphics Synthesizer and SPU2.
with real-time tech demos.
E3 1999 - repeat of March tech demos. at least one stand with interactive / playable demo (GT 2000 i think?) - NO CASING shown
Fall 1999 - (TGS?) PS2 console casing unvealed
Feb 2000 (?) - PlayStation Exibition, PS2 games playable?
March 2000 - PlayStation2 launches in Japan
E3 2000 - PlayStation2 on show floor with playable games
Oct 2000 - PlayStation2 launches in the United States
Don' be so pessimistic and rather look at his:
Kutaragi Ken said playable at E3 so...
On the matter of a release date, Ken would not commit to an exact date, but said the machine will follow a similar schedule to market as PS2.
Using this theory, considering the PS2 was first unveiled in playable form at TGS Autumn 1999, followed by the official 'PlayStation Festival' launch event in February 2000, and then finally releasing in Japan one month later in March, we could see the release of PlayStation 3 in Japan as soon as November 2005 - an equal six month measure from the scheduled unveiling.
