I thought it was really weird when they announced they were coming out with a console (not realize how they worked on the DreamCast and other games.) But I think two of their consoles really pushed gaming technology and advancements. In my opinion console makers would be slowly adding tech if Microsoft had not pushed them with the Xbox and 360. PC would be so far ahead of them down, they would just now be getting to the Wii level graphics or slightly above.
Now they seem to be focused on making money over pushing new ideas and boundaries. Which I feel completely disappointing. Will wait to see what happens at E3 this year, but for the first time in a very long time I didn't get the new launch Xbox this time.
