Little Fighter 3. Hopes and expectations

[A-Man]

seriously though, am i the only one who sees HF as a LF3??!

No, I do too. But the way HF is going now on a mobile platform, and the fact that it can't be modded already puts off a large portion of this community. Hero Fighter is way less popular than LF2, and so is Lucas compared to Davis.
I'd personally love to to see the Little Fighters revamped.

Also u mentioned that this engine support 3D, I think there will be needed to create 3D sprites right?

It supports 3D in addition, so it's not required to use 3D. Plus, I find 2D to fit and look better in such a fighting game. 3D models might prove useful in designing stages (a whole stage can be designed in a single model), and maybe with giant objects which extend a lot in the z-axis.
