user1475: 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?

user238: The system is using integers to represent amounts. 1 satoshi is the smallest unit (integer one). The satoshi is the base unit of the protocol (not the bitcoin).
It would be very hard to change this to support more decimals, but it seems also extremely unlikely that the need arises. With 21 millions bitcoins (i.e. 2,100,000,000,000,000 satoshi) in total, there is already a lot of decimal digits to go around.

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

It is more like the other way around, one bitcoin turns out to be 100,000,000 satoshi.
What could happen is that "one bitcoin" becomes too valuable, and you may want to come up with another name for a more convenient amount, say 0.001 BTC.

user153: The value of a Satoshi is fixed.
The key word is "currently" (smallest currently possible).
If the divisibility is ever increased, a Satoshi will still be exactly 0.00000001 BTC, even though there exists unit representing an even smaller amount.
There would need to be new names for these new denominations that are even smaller than a Satoshi, but dSatoshi (1/10th of a Satoshi), cSatoshi (1/100th of a satoshi), and mSatoshi (1/1000th of a Satoshi), would likely suffice.
