Are there any email changes coming to MarketingHub (similar to the Campaigns ones just announced)?

Are there any email changes coming to MarketingHub (similar to the Campaigns ones just announced)?

Can Zoho tell us if any changes are going to be made to the email capabilities of MH? I ask because of the changes just announced for Campaigns. Obviously, some of the changes to Campaigns don't apply to MH but if changes are coming I'd like a little more than the 1 day notice that was given to Campaigns users.
