It may be possible to search deeper mainly thanks to better algorithms and better hardware. I do not see 64 bits as something important.

No Extensions and pruning and order of moves are the key factors. speed can only give linear improvement when extensions pruning and better order of moves can give exponential improvement(It is better to be 1.1^n times faster when the program searches n plies and not twice faster at every depth).
