i would love this game to have more than one drangon species like the Agathos Daimon,Aitvaras,Amphisbaena,Gowrow,Lung,Pa Snake,Peist,Puk and Liru the list continuse

Which is impossible since in TES lore "dragon" is itself a species from Akavir.

I thought different types of dragons were confirmed?

well we know that these exist:

black dragons know as jills, brown-ish dragons as they appear on the trailer and red dragons like nafaalilargus.

There are going to be different looks in dragons, but they are not going to be puny and ugly like the dragons in the games you listed. TES dragons equals massive badasses.

The dragons in Skyrim are not from Akavir.
