It would probably make more sense for Elex's show to air only on CNN Domestic, and CNNI could keep doing its own thing. But I guess budgets won't allow for that. I'd love love LOVE the old CNN Today to come back from London, and have that instead of Newsroom or The Story Is (ah, the days of Max and Monita! @ginnyfan). But I don't think CNN London has the capacity to do such a thing anymore.
Sundays are actually no longer a working day in the UAE, which I think is why Connect the World went Monday-Friday. (Really it should probably be Monday-Thursday as their working week officially ends at midday on Fridays. But that would probably mess the schedule up too much )
I suspect with the winding down of CNN Max, we'll probably start to see more and more domestic shows on CNNI. Probably by 2030 it'll be more or less a straight simulcast of domestic. Which sucks, but I guess these are the times we live in. News channels are becoming ever less relevant. Sad for us news junkies...
