Depends on the community.
I agree as a community we have the power to keep bitcoin alive for as long as we would like to see it survive...
If they keep dividing, there will be hundreds of coins named bitcoin. I don't think it can survive, but the blockchains' idea will.
If we are going to have more splits in the future that makes those bitcoins altcoins nothing more! And bitcoins survival will depend on whether the btc devs stay united and agree on the best implementation for bitcoin we could go all the way.
