The Marvel comics have managed to take care of long-form narratives that embrace the multiverse and the Void for a while now, so it isn’t fully unimaginable for the MCU to regain their footing, however for now they appear to be on shaky floor.

Fortunately, the good-natured ribbing of Deadpool appears to suggest that the multiverse will now not be a significant component for the franchise shifting ahead, so there may be nonetheless hope to get issues again on monitor.
