At least a /40 should be minimal default for a end-user (not a /48) and a /32 for any size of ISP. For now my personal impression is to create some artificial scarcity in order to have different levels of Service Category.

Glen - 

Issuance of /48 IPv6 prefixes for end-sites are the result of ARIN registry policy that was developed by this community and heavily informed (as pointed out by Bill Herrin) by the 2001 guidance from the IETF contained in RFC 3177.

I will note that since then there has been more nuanced guidance from the IETF in the form of RFC 6177 (2011) that specifically notes that larger issuance should be provided when it makes operational sense – along the lines noted by David Farmer in his reply.

ARIN registry operations follows the policy developed by this community - to the extent that there are different policies for different operational usages, ARIN implements accordingly.
