Though 343 Industries had announced that it would conduct a beta test for its next major content update to Halo: The Master Chief Collection, it appears that the company took a step back from that today. The company said in a blog post that it will no longer carry out the beta test because the amount of extra time and work it would take would ultimately delay the final release.
From 343 Industries:
"After further evaluation, the team has determined that that final testing for the content update will be completed internally, and we will not be conducting a beta test for the next CU. Also, it was determined that the additional time and work devoted to the beta would've actually postponed the public availability of the content update. Lastly, there were some added challenges surrounding the CU beta – including an extra series of required updates and rollbacks - that made us take a step back and reexamine the CU beta. Ultimately, this plan will allow us to deliver the smoothest possible experience, and ensure that the next content update becomes available as soon as possible."
The studio initially announced the beta late last month, stating that it wanted to test the update in an "at home" environment to ensure a smooth release for players. However, two weeks have passed since the announcement without a beta in sight.
There's still no word on when players can expect a final release. However, given the studio's reasons for canceling the beta, hopefully you'll be enjoying its matchmaking improvements on your Xbox One sooner rather than later.
