From what I've read, VS 2008 SP1 and Team Foundation Server SP1 packages are traditional service packs that require you to first install the original versions before you will be able to install the SP.
Is there a way, supported or not, to slipstream the install?

Here's an MSDN forum post in which an MSFTie indicates it will be possible and that details are forthcoming. Another poster is relaying results of her almost-successful attempt. Looks like this will be doable soon.
