A 5 year program map to fielding makes me think this will be a Z10 or Z19 Overhaul.Of course R&D should be a continuous process, a but a new attack helicopter seems a strange choice given that Z-10 is already of more modern basic design lineage than Z-20, Z-18, or even (reading between the lines) the upcoming Sino-Russian heavy lift helicopter.
Anything really revolutionary would need at least 2025 - 2030 and then it would likely be some kind of non conventional rotorcraft like X3, Defiant/Raider, Valor or the like.
