''Xbox games were in HD not the 480p games but the 720p and 1080i games, It was the first HD system."
PS2 too had HD game but neither of the two had full hd and very few hd games.
Also Sony was laying the foundation for bluray this gen.I am not saying that they had this all planned but if you look at the previous media formats,then you will know.
CD - released in 1982.By the time PS1 integrated them in 1994,they were is mass productions d very cheap to produce already.
DVD - released in 1995,by the time PS2 launched,they were 5years old and comparability cheaper
Blu ray - released in 2006,it was launched with the PS3 and had no previous establishment.It had no foundation.They were and are very expensive to produce to date.
Overall in PS1 and PS2's case they had integrated formats which were already in mass production.In PS3's case there was nothing.PS3 actually gave birth and laid bu ray's foundation
