He said the developers need the new consoles so they can start making games for them, it takes around 2 years to make a game with a ready to go engine. So to get a game on a new console if they sent the hardware to a dev you wouldnt see it until 2013. and if they get it next year... thats 2014.
whats one of the biggest complaints about games on the current consoles? lack of inovation. game A looks and plays like game B but only a little different. thats because the hardware is holding games back, to add something new and refreshing they need to take something that was good out to make it run. You cant have shiny new gameplay mechanics on a system that wont run it.
graphics for consoles has hit a brick wall and still dont compare to a 3 year old PC. misconception that better graphics are more expensive to produce. thats utter bs. making a high poly count model is much less time consuming than making a good looking one in a low poly count, plus you need to do more work on the LOD's becaue they will show closer and thus need more details unlike a game that can run on a system that will show the normal model far enough away that the first LOD can be a standard primitives with alpha channels on planes instead of model. thats 2 LOD's that dont need to be created. thats personal experiance with making 3D models.
now lets consider the meat of the graphics .TGA or .DDS. lets see... take a picture of a texture, make it a seamless tile in about 30-45 seconds in photoshop, apply it to the model. done. todays graphics on consoles cannot handle that level, so its take a picture of a texture, an artist completly redoes it so it has enough detail so you know what it is but not so much that will bog down the console, apply it to the model, then done. thats more time and effort. more time and effort costs more money to do. thats personal experiance skinning the 3D models I made.
