I'm curious about that too. I browsed a bit around Amazon Instant after updating my PS3 yesterday and was surprised by the great selection of TV shows and films, way better than both iTunes and NetFlix. Too bad streaming is not actually available yet here in Brazil :/

We're going to add it soon. We just wanted to ship what we've got now.

Sometimes it's a little tricky for us to gauge what's popular with streaming, as we don't get many of the options down in Australia.
