New Star Guardians Bringing A Completely New Map?

I've been looking at the Star Guardian teaser, and I can't place the map. It doesn't look like Summoner's Rift nor Twisted Treeline and obviously isn't Howling Abyss or Crystal Scar.

Twisted Treeline looks the closest to it with the curving lanes, but not much and nothing else really matches the map's layout pattern.

What are your thoughts before the PBE goes up and fully reveals this map?

UPDATE : I've gone through the teaser frame by frame, and it is defiantly not one of the current maps. Ezreal at 1st made me believe it could have been Crystal Scar, but looking closer it shows 2 of those fountains which ruins the CS layout with Syndra's bridge also preventing that from being CS as well.

Looking through the others, nothing shown connects to any of the other locations on any current map.

UPDATE 2 : I WAS RIGHT, IT IS A NEW MAP (series of maps more specifically). This mode looks amazing so far, can't wait to get a hold of it. I'll see you all in "Valoran City Park"!
