Today's build is currently at build 10148, so with the normal speed rate at about 1 new build a day, maybe we will see Pre-RTM as build 10150 on Wednesday this week.
We won't see 10150 since there is a test phase. They never release a build as soon as they compile. I Therefore, probably 10144 is the next candidate.
And that means what exactly? The only thing I want to see is what was just released in the fast ring 5 minutes ago.
10130 has had major blocking issues? No, so also consider this. And then, they are from one step from the feature freeze, there are very less critical bug by now IMHO.
Really wish they would put the AMD Engineering Driver under optional! pissing me off I keep having to reinstall 15.5 even with driver updates disabled.
