Just so you all know, you dont understand divix, their is a new H format of it or whatever which provides Divx to be coded in HD with lossless quality.
The only thing I don't understand is, the PS3 is supposed to be a powerhouse. So, why does this matter to save on resources?
But, as long as no quality is lost, imagine all the extra space on the discs our games can have

.
See, the X360 is doing fine now, but the ps3 is designed to be in the next gen console list still. So when the X360 falls behind, games will be developed for the PS3, of course, Microsoft by then will release another console I'm sure.
