I think the point he was making is that there's no hurry to install SP1 *before the official release*, as there's no immediate advantage either from a security or functionality viewpoint in doing so, assuming you're already running a fully patched and updated system via Windows Update. He wasn't saying "don't install SP1, ever", which is what some people seem to be suggesting.
He was also suggesting that some sources for the leaked RTM might not be entirely trustworthy, which seems like good advice to me.
Ah good point, which only becomes apparent when reading the entire article as it's the last paragraph that puts that in to perspective.
The quote threw me off.
