I have been following these (thinking about the producer).
From here: http://www.youtube.com/watch?v=hwrafpWxxlY
The X32 Compact should be in stores by the end of June to the beginning of July (shipping 6 weeks earlier according to this video). The Producer will be "4-6 weeks later" (End of July to middle of August). The other models (core and rack) will fit between these times.
X32 Compact - $2500.00
X32 Producer - $2000.00
X32 Rack - $1500.00
X32 Core - $1000.00
