'Halo 3' for PC should be ready for public testing in June - Engadget

The 343 Industries team has announced (via Windows Central) that public testing for Halo 3’s Master Chief Collection PC release should start sometime in the “first half of June,” or roughly a month after Halo 2’s release.

You’ll have to enroll in the Halo Insider program (thankfully free) for a chance to participate.

In some ways, this is a particularly important remaster.
