Wait for IDEAS 2008...I have a suspicion that the PK-8 may have changed a bit. POF signed an MoU with MKE (Turkey), and the latter had developed a variant of HK33 called T-50. The T-50 appeared to have been made of carbon-fibre and borrows its scope-design from G36E...it has been 2 years...PK-8 might have evolved into this:

I imagine we'll hear more in IDEAS 2008...I imagine Steyr and Colt will try to capitalize on their respective pilot-AUG & M4 sales to Pakistan...FN Herstal apparently sold F2000 to PAF SSW as well.
I heard stuff about PA studying a possible joint-working-group with POF & a Western supplier to develop a Pakistan specific rifle. Apparently concerns have been raised about future dual rifle use like the present Type-56 & G3...standardization is a major issue. Hence we may see the PA use a rifle-type that would have both 5.56mm & 7.62mm variants in production in multiple formats such as light machine-gun, carbine, sniper, standard, etc.
From a source that is relatively close to the Pakistan-specific defence industry...I heard the HK G36E is on top for this requirement. However PA apparently wants to set-up a JWG with HK and POF to produce a Pakistan-centric rifle for very long-term & consistent use.
For a better idea of what I mean...the Turkish Army apparently raised a JWG with MKE and HK on the Mehmetcik-1. The Mehmetcik-1 is based off the HK-416 & 417, but HK transfered the technology and the end result is a rifle specifically for the Turkish Army. Essentially a project similar to the U.S. XM8 attempt.
Do remember that this would be a costly venture...but I heard the thinking is along the lines of 'very long-term usage'. Remember the threat-perception is changing, the receiving end I suspect will be very large - i.e. MoD, MoI & Civil-Enforcement Depts - and standardization will be key.
