To be fair, both of those points have been known since the reveal. Except for the QTEs I guess. It's a TPS so you can expect the majority of the game to be combat based, but that doesn't take into account the puzzles, the breather moments, and also how well the game integrates all those elements alongside the monster enemy encounters. All of that is important.
From a mechanic point of view, Vanquish was a great game. It's campaign was also incredibly dull and mostly boring however since it had nothing else going for it. The Order may just be mechanically solid rather than revolutionary, but as the sum of its parts, much like something like Uncharted 2, it has the potential to be something great.
Now for people who just want some radically different gameplay, I can see why this initial reveal may feel slightly underwhelming (though I do still feel it's a bit premature) but then that just means it's no different than 95% of games out there. Most games in all genres have similar aspects. Ready at Dawn have given several interviews now stating that they're trying to create a cinematic TPS which comes close to giving you the movie experience with a higher level of immersion than before. A lot of that will undoubtedly be based around that tech aspect, but as long as the combat remains satisfying, fun and well integrated with everything else, and they're able to deliver a great campaign, that'll be a job well done as far as I'm concerned.
Does the game still have the detective bits of gameplay in it?
