Default [Q] Should I buy the dual sim version?

Hey guys,
Should I buying the dual sim version Moto G?
Because there is'nt / not yet any single sim version Moto G here,
I'm considering this:
1) I heard that CM doesn't/not yet support the dual sim smartphone, is that true?
2) Can I use the single sim custom rom on the dual sim version? (It's okay for me even if the custom rom works with only 1 sim card)
3) If I can't install the single sim version custom rom on the dual sim version right now, is there any possibilities that the single sim custom rom will work on the dual sim version someday?
Because I think it's meaningless if I use an android phone, but I can't change anything on it

Any help will be much appreciated,
Thanks
