I had asked basically the same question
9 MONTHS ago over at DJWORX. The response from Louis-Pierre Baudry @ Mixvibes -
"Cross 4 is still in the work so the upside is that there is still time to integrate the feature requests submitted on the forum. I will double-check with our team that our bug fix/feature request list is up-to-date and includes everything that has been mentioned there. You can also let me know if there are any additional/major concerns you'd like to highlight."
Additionally, check this posting, where the exact opposite is believed - that the development of V4.0 has been
stopped -
