I'm beginning to wonder how much Boon really likes the design and the backstory of the characters post MK4 nowadays. From what it seems like, he'd rather make new characters and have them playable over most of the 3D games characters that could be redesigned. Really some food for thought if you think about it.
Ed Boon sure hates some characters post MK4 ..... the direction they (Midway) took in the past, with character design, was hilarious catastrophic in some choices, and Ed Boon knows this .... maybe Ed was not direct responsible , is possible that some pressure and another factores were playing on that past scenario , in what I call "dark age" for MK franchise (MK Dead Alliance until MK vs DC) so, a lot of bullshit and crap stuff were done in MK, in past days .... maybe Ed lost some creative control in MK games in the past, and had to concede in sharing ideias of other people in Midway .... losing a bit of control of his own creation .... we don't know
MK9 can surely be considered the "resurrection" for the franchise series, and so, now, MKX will be the 2nd well done successful chapter in this new MK proposal .....
I admit that some characters, like Kenshi, Havik and Sareena, can be ported well in the new MK reality , but some old characters from 3D era are just corny cheesy and plain stupid, and deserve to be forever in the past games, where they belong
