RTC vs CQ and CC (Score 1)

First of all let me congratulate you on the successful launch of version 2.0 of RTC and 1.0 JF. It is realy great work, thank you and all the Jazz Team. The functionality of Rational Team Concert greatly overlaps with the ClearQuest and ClearCase. Why is it necessary to create a new product? Why not just release it as new versions of old? For customers, it could be easier to adapt. What is the future of CQ|CC, how you see it? Thank you.
