Soon after launch, no.
Sony obviously didn't intend to put these features in, and the only thing that would change that is seeing the consumer reaction.
I can't imagine implementing these things is a quick job, and would possibly only come in (if at all) for the first major firmware revision, not an incremental one.
This is my thinking too. Such a shame. I use the PS3 as a media server all the time. Guess I'll have to have them both plugged in.
