Can Square Enix conquer these issues and save the world?

Those of you who have enjoyed Final Fantasy's previous reinventions on the DS may be dismayed to read a recent Twitter tweet from Square Enix producer Shinji Hashimoto regarding the (hopefully) upcoming remakes of the fifth and sixth outings:

For FF5 and 6, there are technical issues as well, so at present these are also undecided.

We're not sure exactly what technical issues these could be, but hopefully they're nothing that Square Enix can't handle: the possibility of playing these gems anywhere on the go is too mouthwatering to resist.
