I think the world is expecting the Army to acquire the FD-2000. It's not a question of "if" but "when" and, as important, "how many?" Of the three service arms, the Army could have the easiest time adding the FD-2000 since its the bulk of HiMADS architecture is built on Chinese systems (e.g., LY-80).
However, the PAF and PN are obviously trying to keep their air defence efforts under wraps now. I remember at IDEAS 2018 how Leonardo and MBDA were under tight gag orders by the DGDP. Then in 2019 the CEO of MBDA Italy decided to visit NHQ (and possibly AHQ), around the time the PN inked the MILGEM deals.
To-date we don't exactly know what new gap-filler radar the PAF ordered to replace the MPDR. All we know is that it was a $130 m order for 10 units (which can match with any Western radar). We know Italy sold nearly a $1b of arms to Pakistan, but then we have a weird order to build domes for TPS-77 MRRs.
We literally have no idea what they're up to.
However, I'm sure (as you alluded to) the PAF would prefer leaving the IAF ignorant. Currently, the conceited think the PAF only has older SARH-type Spada 2000s at its disposal. The PAF would rather those people forget about the risk of a longer-ranged ARH-type, much less a long-range SAM (that might be the groundwork for an eventual ABM-type system much later on).
In any case, when the armed forces started building ADGE in the 1980s, it was a hi-tech but otherwise innocuous asset. So the PAF was relatively open about the systems it was inducting and, to an extent, how it was deploying them. However, nowadays, air defence is slipping into a more opaque realm than even the fighter programs (e.g., we'll likely learn more about AZM in the coming years than the HiMADS evolution).
