tl;dr: Yes, you should be able to.

XSEED Games/Marvelous makes all games they publish available for download on a game's respective platform. So yes, unless Extella is the only exception to their usual policy, you should be able to download it from the PSN Store when it's available.

There are too many horror stories about how bad Sony's servers are for me to recommend downloading it, unless you're ultra-patient or have really fast internet. You should look into buying the disc from online retailers like Amazon, or your regional equivalents of Target/Walmart (especially if you can dish out the extra cash for the limited edition).
