In reply to a tweet, Gabe Aul has talked about couple of good Windows 10 Mobile builds under internal testing. The best part is that Microsoft is considering to push a new build later this week to Insiders in Fast Ring, though it may still depend upon the final testing results in internal Microsoft rings. But since there are “couple of good builds” we may have all the reasons to be optimistic.
@JimmyNg66067250 We have a couple of builds that are looking good in internal rings. It’s possible we’ll see them later this week to Fast.

If this happens then Microsoft may be planning to push new preview builds more regularly before it finally signs off one of them. The last preview build was Build 10581 and you can read our impressions of the build by clicking here.
