The short answer: it may.
You may want to keep both versions on your PC as you make the transition.

Well, that makes me nervous. Let me ask you about keeping both versions.
1. If I install 2007, does it give me an option to keep 2003? If it's tricky
to do I don't want to risk it.
2. Does it overwrite all the presentations when installed?
So, I guess my question is, how do I install 2007 and preserve my old slides
and formatting?
Thank you.

When you install 2007 it will automatically set the file extensions to open
using 2007. This means if you click on a PowerPoint file, it will open it
with 2007.
When a 2003 file opens in 2007, it will use compatibility mode to make it
compatible with 2003. It won't change anything unless you specifically click
to edit the item (such as graphs) in the 2003 file and there's no going back
to a pure 2003 file once you say ok to change it.
This isn't neccessarily a bad thing and in many instances it improves the
presentation.
I'd probably make back ups of my 2003 files onto an external source (just a
suggestion).

In addition, make sure you install a Windows-certified printer driver on the
computer (not on a network). Without it, we've seen reports of things
shifting on slides and other oddball display issues. The printer driver
resolves this stuff.
See PowerPoint 2007 text editing slow, text cut off, text display or
formatting problems, print, crash problems

(You'll find a link on that page to instructions for installing a
Windows-certified printer driver.)

In addition to what Glenna said, when you install Office 2007, use the
custom installation option. There you can tell the installer to keep the
previous versions. You'll have to choose one or the other version of
Outlook, though, because you can only have one version of it installed on a
computer. (I like Outlook 2007 just fine -- better than 2003, actually --
but I admit I am not an Outlook power-user by any stretch of the
imagination!)

In addition to what Glenna's said ...
Ah. Echo's said it already. Nevermind.
But ...
Another approach, if you have a computer with enough oomph to support it, is to
install 2007 into a virtual machine.

Steve,
If I install VPC to test out PPT 2007 how much RAM would you allocate. I
have 4GB on my computer.
Thank you.

I have 2G, and 512MB for a VPC worked best for me. I originally allocated
1G, and it was almost unbearable. Not sure what to do with 4G, although this
FAQ might help:

1G was unbearable. Do you mean your host was too slow?

The advice I've read (and it seems to have worked out for me too) is to limit
it to 512mb or so.
