Good question :) I suspect the underlying interface to tabular material will remain rather similar. (Although I'd like to write a better *user* interface, one day.) Either way, I can't see anything happening in the near future since porting array would be a big job and maths is all rather up in the air at the moment. (breqn is taking form but it's very early days yet; it's current incarnation on CTAN is probably the last that *won't* use the expl3 bundle, though.) But there's no problem, of course, using their "LaTeX2e" macros in your package. W
