It's marketing is just fine with me. MK had a similar approach in 2011. Trickle out info and footage a couple times a month leading up the the game, and when you get closer, like in the last month, kick it into high gear. People complained about MK's marketing, yet it did just fine in sales. When it came game time, there were ads on T.V., ads all over gaming websites, in magazines, even billboards in big cities. I see it going just the same for this game.
I personally love that strategy better. Not revealing everything until closer to the game also helps keep it feeling far more fresh when it actually comes out, and excitement and anticipation at it's peak. Back with the likes of MK

A-MKvsDC, we already had seen TONS of gameplay footage, all the characters...2 months in advance. It just felt like "seen it all already" weeks before the game came out. Whereas with this and MK(2011), it actually keeps you guessing and speculating(which is most of the fun for a lot of us) all the way up 'til release.
So yeah, in my opinion, the marketing is excellent. I know once mid-late March rolls around, this game will have ads all over the place, and word will spread as if most comic book fans and fighting game fans don't already know if it's existence.
They know what they are doing. They are taking a more paced out approach. As I said, MK(2011) had the same approach, and people were complaining about the marketing for it as well, and yet it's sales and reception was superb.
