No word yet from Modern Tribe on this so I wrote a patch for now. Just add this snippet to your theme functions file and those two meta values will be returned in the event object as they were before:
add_filter( 'tribe_get_events', 'mdw_add_back_EventEndDate', 5, 1 );
function mdw_add_back_EventEndDate($events){
$updated_events = array();
foreach($events as $event):
$event->EventStartDate = tribe_get_start_date( $event, false, 'Y-m-j g:i a');
$event->EventEndDate = tribe_get_end_date( $event, false, 'Y-m-j g:i a');
$updated_events[]=$event;
endforeach;
return $updated_events;
}
