A few years ago, when Adobe bought out Serious Magic, I was excited and hopeful that they would bring the vector keyer from Ultra to the Mac. So far, they only shipped a rebranded version of the Windows only Ultra with the CS3 release and then completely dropped it for CS4.
If the vector keying engine from Ultra is included in After Effects in CS5, I'll buy it. That all by itself will be worth the price of entry.
On the graphics and web side of things, I agree that there should be some more serious competition - especially on the Mac side. My go-to application has always been Canvas, but when ACD bought out Deneba, they killed the Mac version.

The last version of Canvas made for the Mac will still run on Snow Leopard. I'm used to its quirks but it really kills me that it was discontinued for Mac, since I can get work done fast in Canvas.
If I had the cash, I'd buy Canvas back from ACD, tear it apart and fix the bugs I'm so familiar with and maybe buy the rights to the excellent but currently comatose TypeStyler and add those features to it. Oh, and I'd drop the Windows version out of spite.

(OK, I wouldn't but I would enjoy thinking about it...)
