One of my favorite sound designers has a brand new library for Reason out - Thorkit II:
"ThorKit II for Reason 4 and above, the sequel to the popular ThorKit ReFill – 200 new Thor patches! ThorKit II contains 100 lush Chord patches, 50 evocative Polysynth patches, and 50 driving Sequence synths. Chord patches use Thor’s Step Sequencer to mimic Chord Memory, a function found on some synthesisers whereby pressing a note plays an entire chord, resulting in some huge sounds. You can deactivate the chord with Button 1 and use these as 100 deep Polysynths if you prefer."
