I was also surprised at that part of the article. Everything else (and of the site in general) looked very good.
If you'll excuse the comparison, that part of the article looked like something I'd read on the Inq (or rather, copy/pasted in these forums). You clearly say you're not sure, but the take away message is that there's something dirty on ATi's PCI-express solution.
It's like the INQ recently saying things look 'cloudy' for nVidia but quickly saying they're not sure that's correct.
It might be true, it might not. Until you're sure, I'd expect you to hold on to that information and keep researching. That's what I expect from general reporters. They don't print/open news with "we're not entirely sure but we think there are WMD, look at these two pictures".
If you have the smoking gun WRT ATi's hypothethical deceit, fine, print it, I'll be very happy to know that. If you're not sure, don't cast doubts because that will be the take away message. People will say "watch out for ATi's new cards" instead of "there's a chance ATi's new cards won't be native PCI-express but the jury is still out until they are benchmarked."
The details of your doubts will be lost and soon enough fanATIcs will begin to label your site nvidia-biased.
