When will Sony give us a new PS3 Update?

I also don't understand why the PS3 doesn't upscale SD content (typically the extras) on BD as it does for SD on DVD.
Apart from the quality increase, if everything was upscaled to 1080p, it would also remove the annoying problem of switching resolutions. My Pioneer Plasma doesn't respond instantly to the change, and refuses to stay in dot-by-dot mode, so I often have to set this manually.
A little thing, but annoying non-the-less !
