Plans for more allowing more than 2 other regions for secondary clusters in Elasticache for Redis Global Datastore?

Hello,

Thank you for using Elasticache.

As you mentioned, Global Datastore in Amazon ElastiCache for Redis is currently limited to two cross-region replica clusters. We do not comment on launch plans or incoming features. I have submitted your feature request to the Elasticache team, so they can prioritize their work according to customers necessities.

I suggest regularly checking https://aws.amazon.com/new (or subscribe to the RSS feed on the same page) for services and features announcements.

I am sorry for not being able to provide a more detailed answer at this moment.
