64-bit Unity Editor: What's the big deal?
I heard that Unity 5 will ship with a 64-bit editor. But I don't understand why that is such a big deal. I've heard people begging for this feature. But what really is it? What are the advantages? What is its difference with the current version of the editor (32bit).

This is simple: maximum available memory. This is mostly important for building when big link cache is prepared.
A 32-bit system can allocate 4 GB of memory. That's chicken feed these days. A 64-bit system is capped out at 18,000,000 TB.
That's the main difference everyone is excited about. There other advantages too.
See wikipedia article that explains very well the differences, including pros and cons:
