Purva Emerald Bay: RERA vs Target Possession Dates?

Came across this video about Purva Emerald Bay in Keshav Nagar. The 2BHK sample flat looks decent, but one thing caught my eye. They're saying RERA possession is June 2025, but target possession is Jan 2024. That's a pretty big difference, almost a year and a half! Not sure if this is normal for Puravankara projects. Has anyone else seen this type of timeline? Kya scene hai, is it realistic to expect it by Jan 2024?
