Yes. I'll bet that stimulates a lot more worldwide availability since the products that the micro-SIM is in are/will be two of the most ubiquitous and sought after SIM-bearing mobile devices in the world.
I'd guess micro-SIM was designed back in the days when it was assumed that the holy grail for cell phones was going to be smaller and smaller. With the ascendancy smart phones, they had to have a usable screen and a keyboard, so they got bigger again and the smaller form factor of the micro-SIM became less important. Who knows why Apple decided to go that route now, but no doubt it will have an impact on micro-SIM availability as well as adapters and probably cutting dies.
