I just received an email from one of the developers at Microsoft about their Office 2007 blog. Because Office 2007 is now in public beta they are able to talk about more of the nifty stuff it has. They are planning 3+ posts per week specific to PowerPoint 2007 and the new Office Art capabilities, which should prove to be good stuff to read. Visit them at https://blogs.msdn.com/powerpoint.
