So... Going Rogue...What is it?

Imho Going Rogue will need to add as much mission/TF content as CoV did in at least 5 zones (one for every ten levels) and with some new map tilesets - and hopefully have story arcs written to the very high standards that the CoV/Faultline/RWZ arcs set (i.e. higher quality and more characterful than 99% of the blueside stuff) - or it's not going to be worth paying the same price for (though I probably still will - I'm that desperate for any new Dev-created content).

The side-changing system is probably quite complex - maybe akin to the amount of work that went into adding bases in CoV - but on top of that CoV also had 5 new archetypes with loads of new powersets plus tons of new costume items (it more than doubled the number of costume pieces available, iirc), tilesets and map layouts, and badges.

So I hope we'll get 5+ big zones, as many missions as CoV+I7 and at the same level of quality for all levels 1-50, the side-changing system, at least 5 new co-op TF/SFs set in Praetoria, at least one new archetype, more new powersets (we know we're getting two new ones - I hope they sneak in a few more), lots of new costume pieces, and the L50 progression system as well. That would be worth the same box-price as CoH and CoV had.

I also hope that new players buying GR will be able to play it without needing CoH & CoV (maybe they'll even get access to CoH/CoV zones with it) and then it will also function as a way to get more new players into the game with a single new box purchase, like other MMOs do with their "Gold"/"Complete" versions.
