So does this mean that there is still a chance for 1 GB devices which were left behind (such as the 525)?
Sorry for all the confusion.
Better for you to google to past official Windows news, or Windows Central itself news. Don't follow click baiting sites.
I fear not for 525, old SD400 Platform doesn't work well
I repeat, you perfectly join Windows Insider Release Ring, that's the same Threshold build as official for now, and you can test it for yourself.
Most X2X serie owners use it, with different results
