Not really. If they release a new miner that's an order of magnitude more efficient the difficulty will shoot up as soon as enough units are online.

Hmm. I thought I remembered reading something about two weeks, but that's the time period required without enough blocks to make difficulty fall.

It adjusts every 2016 blocks, but if new miners come online that could in theory be mined in a day instead of two weeks.

I haven't looked too closely at how difficulty adjusted after previous order of magnitude efficiency gains, but the risk is certainly there.
