Do you have a proof of less time and less money? The budget of CoD Modern Warfare can be found here:
https://en.wikipedia.org/wiki/List_of_most_expensive_video_games_to_develop
It is $50M on development only, i.e. a little less than one half of SC's total budget.
The fact that they have shown MoCap stuff probably does not prove anything. I.e. they have probably shown how they filmed several scenes for the game. But this does not mean that we are getting the movie only. We are yet to see. I doubt that there are going to be many people happy if they get FPS instead of a space sim.
It is hard to say anything now. We have only seen some trailers. It is hard to get the idea of what the game is going to be basing on the trailers. There is little info about physics, flight models and a lot of other stuff. Most probably you are going to use KB/M setup for everything CoD.
The scale is different. SQ42 should feature an open world with multiple systems. What CoD is going to offer? Is it going to offer such freedom? Or is it going to be the same as previous games of the series with linear progress? There is no answer yet to a lot of questions.
As for the release date, it should be release when it is ready, and when the release would fit better. I.e. CIG should fit the release in the right moment of time to avoid competition with other projects.
Its pretty funny, even when the evidence is right in your face some of the hardcore CIG defenders are in denial.
But lets do this just for the fun of it.

In this way, "you can be boots on ground, fighting through the streets of a city on earth, call down your Jackal, get into it, fly up through the atmosphere, engage in a dogfight over the orbit of earth, finish that dogfight, land on the deck of the carrier, get into the carrier, go up to the bridge, and order your ship to go to the next mission and all of it happens seamlessly with no loading screens."
According to Minkoff, Infinite Warfare will offer a seamless experience in which players are fully invested in not only their character, but also their vehicle. "It's kind of the Top Gun fantasy," he explained, noting that "it's your fighter that you get to upgrade and customize. You get to walk along the flight deck and have the flight crew preparing it for you and saluting you and you get into it and you fly out into these crazy missions that you chose to go to."
Instead of fragmenting the game by shoehorning in vehicle sequences, "they are seamlessly woven into the fiction of the character and the mechanics of the game," providing an experience that Minkoff described as being "completely holistic."
SQ42 no COOP as promissed, CoD IW including COOP
Otherwise its going to be the same, story progressing campaigns, sometimes on rail scripted events.
The scale is different. SQ42 should feature an open world with multiple systems
eh? no, SQ42 will not contain anymore open world than CoD IW, you are here talking about SC and that is another game.
Development time CoD IW 3 years and less than $100 Mil. going online November 2016
SQ42 development time 4 years and counting, release ? who knows, but its not going to be this year for sure.
