I bet it will, the other parties aren't in favour of a referendum as they don't support pulling out of the U.K. Last time around they only voted the bill through as the SNP had a majority and therefor the vote in the Scottish Parliament was a formality. Without that majority the other parties will oppose a referendum.
The vote was also only put to the Scottish Parliament after an agreement with the U.K. Government that allowed the referendum to become a legal process, as it stands there is no way that agreement will be made before Cameron steps down and an incoming PM will be prioritising EU negotiations. The U.K. Government would have no interest in making it a quick process, so even if it appeared the SNP had convinced other parties to back there proposal it wouldn't simply be a straightforward process.
There are several hurdles in the way of getting a referendum for Scottish independance and even then I expect the referendum would go the same way as last time.
I wouldn't deny Scotland anything, Scotland had its chance to leave and chose to stay. As a Brit of Scottish and English heritage I was very pleased with the decision last time around as I identify strongly with both nations and felt it was the right decision for Scotland. As things currently stand the union is even more important to Scotland than it was then.
