What new features are you hoping for, Pika?
As good as iLife 09 is, there's still a lot of improvement that can be done:
1. iPhoto:
Allow users to merge/split libraries with edits/tags/info intact. I know there are utilities for merging, but this should be a no-brainer, considering more and more people are owning multiple Macs. For example, I want to carry some pictures on my Macbook, but I don't want to copy the whole iPhoto library. Also let's say after travelling, I have a lot of picture in my iPhoto library on my Macbook, and I want to merge them with the iPhoto library on my iMac (including edits, tags, etc). Sure there are workarounds, but shouldn't Apple make things simpler?
2. iMovie:
-Better integration for videos from iPhoto. For now, videos from iPhoto can be a mess in iMovie after merging/splitting events instead of following the logical grouping (eg. by Events per iPhoto).
-More effects, especially the ones that were gone from iMovie HD (eg. the N-square)
-Better control on text such as custom placement, or at least allow user to adjust the text placements of the existing presets
-Custom background (something as simple as custom color background)
3. iWeb:
-Integration with blogging services like wordpress.com/blogger (come on, MS can do it with Live Writer, I'm sure Apple can do better).
I don't use Garageband nor iDVD, so I cannot comment on those.
