to kind of squash the rumor mill (and as legit as some of the TR3 paper rumors sound), It wasn't too long ago that everyone was dead certain there wasn't going to be another TR anytime soon. Literally every tech site was acting like this was the case, and then shortly thereafter Lisa Su killed that rumor saying "we never said that. That was a internet thing.' We have to remember, literally every site was *certain* there wasn't another TR coming this year and some going so far to spout that they killed off the TR line over whatever reason because some credible source said so. And just like that.... poof. Squashed by AMD and here we are a week or so away from a new TR launch.
So when I see all these 'credible sources' and sites talking bout how TR3 isn't going to support X399 drop-in, or how there's all these variants of these 280w multi-form factor & redundant boards and even the CPU itself (i mean, what, they are releasing a 16c Ryzen 3000 and a 16c TR3 to the consumer market on the same day? doubt it), I just look back at how wrong everyone had it about TR3 even being a thing and I think there's probably a lot of bad information going around yet again.
I'll guess we'll find out soon enough, but wouldn't be so sure about anything yet other than 'It's Coming'.
