In a separate post I asked about the wire type for a sub panel feed. The Loads I am feeding are all straight 480volt three phase loads. I am installing a sub panel to have a little extra room for future expansion. Should I pull a neutral conductor for some future unforseen 277 volt load. I would need to upsize my pipe for the added conductor but that is not the end of the world as I think it would make pulling easier.

You would know more about future loads, or the possibility than we would. IMO, I would pull the neutral. From past experience, someone will come along later and ask for a circuit that requires one. Then you have to explain to them why you didn't pull one and why now it will be more to do so.

Some projects or customers will have no need for neutral load in the foreseeable future, if ever. Others, it never hurts to have one. As stated before, know your customer.

Other factors to consider:
1) How difficult would it be to increase the size of the conduit now but pull a neutral later (time is money, so you can justify increasing the size of the conduit simply to have an easier pull)
2) Would there be value to pulling a reduced or even minimum size neutral?
