If Moore's Law comes to an end this decade, we might see engineers think of smarter ways to make devices smaller and smarter, perhaps maximising the computational power of existing chips. The electronics might hit a snag, but I think it gives lesser advanced societies time to catch up while we think of ways to innovate again.

Using depreciated Fab is so appealing when the price of new fab is becoming redicuously high so this trend will continue. Now regarding analog stand alone vendors I think there is room for growth in the future especially in the smart grid, solar convertors, electric and hybrid cars etc.
Analog chips for RF and PMU paired with ditigal ICs on handheld devices is actually diminishing with SOC initiatives even though the market for these devices is skyrocketing, in fact because they are skyrocketing. As such I would argue the analog pure-play vendors are in danger of losing their shirt. As for Moore's Law, 3D and using already depreciated older fabs, all valid points until you need 32 cores.
