Photoshop CS4 Lack of 64-bit Support

So I don't know how many of you out there were up this morning to watch Adobe's online release of CS4, but it was an exciting moment. The smart resizing, enhancement of blending modes and non-destructive edits is awesome.
My one gripe however is the lack of 64-bit support for mac. Now I know this won't affect most users, but I personally am sad. I bought my computer for power-housing, and was looking forward to Photoshop being able to access all 9 GB of ram in my computer. Alas though, it will still be limited, at least until CS5.
Adobe does say that the 64-bit version in windows isn't that much faster, but it still leaves me pouting.
Overall though, I am excited for the new features.
