Jason Shreier at the other site:
"I can confirm that this Cerny thing has been in the works for a bit. They had been planning to do a PS5 thing at GDC. Also, soon we'll have confirmation of what I've been saying all along -- that both of these machines are extremely powerful -- and then maybe everyone here will stop tagging me in all these dumb next-gen console rumor posts. Teraflops be damned "
What likely happened is both MS and Sony did their own next gen promotional work as online videos since GDC was canned.
MS did a lot of legwork since you can tell it involved more than some last minute stream. When you got a coordinated PR bit from MS, and DF guys it's not like they did it all Sunday afternoon and uploaded everything Monday morning.
It's GDC week anyway, and MS already confirmed they were going to do a video (something about MS Stack), so it looks like over the last few weeks they added dedicated SeX articles and videos too.
Sony bailed from GDC. But looks like their plan is to do an online info session as well. As someone pointed out, Sony Japan says Cerny is going to stream what he was going to talk about anyway.
So it looks like both companies prepared to talk consoles during GDC week, but just by coincidence MS went first (or MS got word Cerny was Tuesday and purposely did a Monday morning release).
Either way, MS spilled the beans and it looks like Sony will spill the beans tomorrow.
So why all the cloak and dagger on who/why which company goes first?
