What they got right: I don't have much to say here, as it's a set-up story. Still, Ian Flynn does a good job setting up the future Mobius and the place of our heroes. Apparently, this isn't the first story to take place in the future, so it catches us up to the new timeline (altered due to events in older Sonic the Hedgehog comics, according to the Sonic Wiki) and prepare the story, which I assume takes place in the next three issues of the arc. I like the fan-art section, too.
What they got wrong: Current events in the main series seen to contradict much of what happens in any version of the future. One couple is split, there's no indication of another being a couple or really knowing each other, and Knuckles doesn't have a cybernetic eye like that last I knew.
Recommendation: This could prove to be an interesting story, but hardly the entrance to the Sonicverse that the previous arc was.
