Bridge vs Lightroom

This Adobe products are very different, but...

At first, either of them have raw converters(Bridge has Camera Raw).
They have different cataloguers, but they have!
Lightroom has web site generator, but in new CS4 version of Bridge this function is included.

I know about some small good features, which has only Lightroom, but maybe Adobe will include them into next version of Bridge? Maybe... Since CS2 version Bridge becomes more identical with Lightroom. It's a bit strange :-)
