Spectrum Shift has a line on RPGnow named "Colors of Magic". There are twelve colors, but only four are available yet. I've bought them all, but I haven't looked into the books, so I don't know, how good they are (or, if the arcane/divine-Divide has been done away). The only review I've seen sounded promising.
Another product, which divides magic in a new way, is "Elements of Magic Revised". It presents a new magic system, where you choose spell lists, which give access to enhancements. The spell lists are mainly sorted after the action type, like Evoke, Move or Heal. Every enhancement, which does damage, is somewhere in Evoke - this is true for every enhancement. To create actual spells, these enhancements are combined like lego bricks (within a certain limit). There are even four magical skills, which are usable in spells. I haven't seen a better magic system yet - with a small fix it does even entirely away with the multiclassing problematic for casters, included the mixing with non-caster classes - without the use of dual-caster-PrCs and feats like Practiced Spellcaster.
