Time to divide Pakistan?

Interesting article on Sify.com by Vijaykumar S. Kasi on what needs to be done with Pakistan going forward.
His break-up looks like this:- (image location from sify article).

Don't know whether this would be allowed to happen by the dominant Punjabis.
But already FATA and NWFP has slipped out of the current Pak's grip.
What is left is Baloch and Sindh, which may be difficult to break free as the left-over Pak will not have any access to the coast. More likely is that Pak's real western borders will be a thin sliver of land along the Indus river + Baloch, where the Pak govt can still retain control. The rest along the Durand line would remain a nebulous region, with militant strife or be incorporated into Afghanistan if the Pashtuns align themselves with a strong ruler in Kabul (unlikely).

In any case, the next 10 or 20 years will determine whether Pakistan is able to pull itself back from the cliff or will it start to implode from within.
