I wholeheartedly agree with your analysis there, Lucika. Yes, we should have spent much more time on this. Well, the timing is indeed off in the later missions, but at least they played out reliably, and here comes the already-mentioned "loss of motivation" excuse (from my part), and Shadow was very busy throughout the dev period.
I hope that those that played the original view the revamp in a more favorable light.
As for the last mission: I'm nearly 100% convinced you didn't play the latest version of it, because the end cutscene should have played out somewhat differently and the Other Big Event should have happened much sooner than it did. The stealth fighters kept you distracted from following the events, unfortunately.
CoW2 Revamp will be different than this. I don't know if it'll be better or not; Shadow is reworking the last two missions completely, but I don't know how different they'll be from the originals, because I haven't seen them yet. Shadow has been AWOL again for a good while now.
