Best URL for international domain

[FXDD]

Hello SEomozers

We have a site with this structure:

-www.xyz.com   US customers, limited content in12 languages,

-global.xyz.com  for International customers, full content in 12 languages.

The global site is the hub for the rest of the world.  We are creating a new site from scratch and want to consolidate the two domains in one by using subfolders, such as:

www.xyz.com  for USA,  www.wyz.com/jp   for US customers reading in japanese

and

www.xyz.com/int-jp  for  customers from Japan (international - will set geo location with webmastertool)

What do you think would be the best naming convention for the international?
www.xyz.com/int-jp  or
www.xyz.com/eu-jp or
www.xyz.com/eu/jp or
www.xyz.com/ ...any other suggestions?

I hear you. Do you think I could do it like this?

www.forexDotcom:  Left selection other countries, right selection only 4 languages in the US

We have large number of US visitors going to 4 language pages, we could offer limited content and call to action for these...and get rid of low traffic languages

Do you have a couple of samples of sites that do a good job targeting international and US?

Having one language on your root domain and others on seperate folders includes complexity with no value. Push us customers to xyz.com/us and follow that for everyone else

Complex content duplication problems lie ahead for you! think about how many combinations of language pages you are about to create
