Talent/expertise is not an issue for Pakistan, it has it locally and can certainly acquire it from abroad if necessary. The main issue Pakistan has is finances and lack of foresight - by politicians of course. I hope things change fundamentally in the political and economic department, but for now focus in Pakistan will likely be given to the following:
1. Further improvement of cruise missile technology: namely extended range, ability to utilize it from land, air, sea and sub-sea and nuclear warheads. I think the Ra'ad ALCM will see further changes in its airframe - i.e. stealthier like Storm Shadow/Black Shaheen. We should be seeing another type for use on submarines and potentially even future frigates via VLS. While satisfied with its inventory of AShM, Pakistan should consider long-term development of a longer-range AShM with Turkey - for post 2020 use.
2. Tactical air-to-surface missile technology. It is imperative for Pakistan to develop its own series of AGM - i.e. our own Maverick. The recent deal with Brazil's Marcom for the MAR-1 ARM w/ToT (PakDef) is a clear step towards that direction. Minus its seeker, it is essentially a standard air-to-surface missile, and Pakistan would only need to change its seeker, guidance, etc. This should not be an issue as it would have developed this technology earlier via the Ra'ad, H2 & H4, etc.
3. Another possible step in tactical development would be the development of our own JAGM-type missile. Essentially an air-to-surface missile that is light enough to be carried on attack helicopters, fighter aircraft and armed-UAV. Again, this shouldn't really be an issue as Pakistan has not only the know-how, but also doors of cooperation with South Africa, Brazil, Italy, Turkey and of course, China.
4. Development of next-generation air-to-air missiles. This is a clear requirement as it is an integral aspect of ensuring JF-17 & FC-20's full lethality. IMO a likely avenue to pursue this would be with South Africa and Brazil, initially with the A-Darter WVRAAM, and then later the T-Darter BVRAAM. The A-Darter and T-Darter are AIM-9X and Meteor standard systems, respectfully.
5. Surface-to-Air Missiles. Not much has happened in this department, but there is some movement. Namely the interest in further developing FT-2000/HQ-9 long-range SAM. However, Pakistan should also look into developing a solid medium-range VL-SAM with South Africa - perhaps based on Umkhonto-R - with an aim range of 30~40km. Not only would it bolster land-based AD, but also naval-based as this system could be integrated on frigates & corvettes via VLS.
6. In strategic terms. The development of ICBMs and MIRV will continue in its theoretical and capacity scope - i.e. the ability - but the physical development may not occur for some time. In fact, its development may have been synchronized with the Satellite Launch Vehicle programme. Nonetheless, it is clear that WMD-development is in due course; recent news of Pakistan switching over to plutonium-based nukes, arming cruise-missiles, etc.
