Sort of, and no, you don't need to.....
The important points I'm sure Apple will cover with "Snow Leopard" are the details of what has changed "under the hood" to allow it to be faster. A side-by-side comparison? Sure, that will be part of it. But there's a lot of room to explain how the new technologies inside actually do what they do, allowing developers to easily code apps that balance their load over multiple processors and so forth.
(Something like moving from EDGE to 3G is a lot less interesting to explain from a tech. standpoint - because by and large, cellphone owners really don't CARE about the details of how the cellular signals differ from each other. Computer users have more reason to care, because some want to write their own software. Others are simply so used to hearing the "It's faster!" promise thrown about, they want more details of WHY they should believe the statement.)
But no, you have NO reason to give up on the G5 for a while! That's still a very nice machine, and can hardly be distinguished from the latest Mac Pro towers at a first glance. I owned one, and decided to resell it and get a new Mac Pro -- and honestly? 80-90% of the time, in regular daily use, I can't tell I even switched machines. It's nice being able to run "Intel-only" apps that pop up here and there, and it shreds through things like video transcodes. But let's face it. Most of us spend more time just surfing, checking email, a little bit of work on a web site or playing some music in iTunes... whatever. The G5 will feel PLENTY snappy doing all that stuff, to the point where a Mac Pro seems about the same.

I hate to be a downer but isn't this really just going to be a side by side performance show of how much faster Snow Leopard is on an Intel Mac than Leopard is on the same machine? Kinda like "Ooooh look how much faster 3G is over EDGE!!!"?
But don't get me wrong, I'm really hoping that's all it is and that there are no real new features added just yet.
I'm not ready to give up on my PowerMac G5 as my central hub for all things Mac in my house. I won't have the cash to replace it with a Mac Pro, or even high end iMac, until late 2009/2010.
