Is the value of "satoshi" fixed or dynamic?

BitCoin Wiki (Transactions) states:

 

...1 BTC = 100,000,000 Satoshi...

Yet BitCoin Wiki (FAQ) states:

 

..."satoshi"... is smallest denomination currently possible

In the future when the protocol decides to support more decimal places, will the value of "satoshi" change to match the smallest denomination then possible?

Or will the value of "satoshi" fixed at 0.00000001 BTC?
