Pre-launch offers in Mahipalpur — real deal ya just hype?

Did a site visit to Sk Builders And Developers' new project near Mahipalpur last week. They're pushing pre-launch offers big time, saying these are the 'best prices' we'll ever get. But honestly, I'm finding it hard to believe. I work in this line, aur pata hai builders ka game. My budget is around ₹1.5 Cr for a 2BHK, and they're quoting ₹1.3 Cr for pre-launch, but with all the PLC and hidden charges, it’ll easily touch ₹1.6 Cr. Should I jump on this pre-launch, ya wait for the actual launch and try to negotiate a spot discount? What's been your experience with pre-launch pricing in Delhi, especially for projects in areas like Mahipalpur? Does waiting actually pay off, ya builders just hike prices later? Trying to maximize my ROI here.
