Delta 2 Greater Noida: Connectivity Hype or Reality?

Just watched this video on Delta 2 plots in Greater Noida near the Yamuna Expressway. It talks a lot about how well-connected the area is, especially with Knowledge Park 2 Metro and the universities like Galgotias nearby. Also mentions the upcoming airport and Filmcity. I'm curious, for those who know the area, how much of this connectivity and amenity access is actually there on the ground today? Does it feel like a developed zone yet or still very early stage?
