Pune New Launch Projects: What are the hidden risks?

Visited a few New Launch Projects in Pune this past week. Honestly, fed up of renting, landlord raised rent again, so finally taking the plunge. Looking at options around Wagholi and Undri, some seem really attractive for first-time buyers. But I'm seriously worried about hidden risks with these new launches. Heard so many stories about possession delays. Is that still a big issue in Pune? What about builders adding sudden charges like PLC or extra floor rise later? Or not getting OC on time, leaving owners in limbo? Has anyone faced major quality control problems after moving in? Any specific red flags or builders we should be extra cautious about here?
