The PS3 does indeed play divx from burnt DVDs. You can also stream to the PS3 by using TVersity of something similar.
The BlueRay player has just been updated to support BD2.0(?) which is the latest version of BlueRay and allows for Picture in Picture and Web Enabled Content. Basically, everything that HD DVD did out of the box
Now we just have to wait for some BlueRay films to be released that have these features.
For the price, the PS3 is easily the best BlueRay player you can buy on the market at the moment.
I'm actually tempted to get a second one for downstairs
