Are you kidding?
JWs were just banned in Russia and it's not making big news! So it depends where you're talking about.
At any rate, per the Bible, formal religion represented by the Lamb-Dragon Beast (JWs) and the 666-Beast (trinity-believing Christendom) will both be destroyed rather suddenly in the lake of fire. The circumstance is Russia demonstrates just how a religion can be shut down and its facilities confiscated overnight. We enjoy the practice of religion in free countries but there is no guarantee under extreme circumstances those rights will be abolished. For instance, when martial law is in effect, normal feedoms of assembly or even communication are curtailed or suspended.
But that is just public expression of religion. Perhaps the real question you're asking is will the Bible become obsolete in 100 years? Will people stop believing in a god?
The answer to that is, of course, no. By then the millennium rule of Christ will be underway. But there will be only one religion at that time, whatever form of Christianity under Christ under these new circumstances. The new religion will be worship of God and Christ.
So false religion and corrupted Christianity will definitely disappear, probably when Babylon the Great is destroyed by the UN, which we expect can occur at any time, especially within the next few months leading up to March-May 2010. But how can you stamp out a belief, even if you remove the physical church building and make assembly illegal?
But as a direct response, NO, true religion will never disappear.
