New Language: Chinese or Japanese

[chisness]

I'm going to be a sophomore in college next year, studying engineering. I've got deferred admission for an MBA after I graduate and do a couple years of work.

I expect to do something with business/engineering.

Will it be useful to learn Chinese or Japanese? Which one will be more useful in, say, 10 years? I know Japan is big now, but it seems that things might be moving China's way.

I'm looking to probably use the Rosetta Stone software -- any opinions on this?
