Well they can't control how long the exchange takes to review the code so postponements are something to just deal with and the community is at least being regularly updated. Again though - why is there any rush for it to be on an exchange in a bear market, much better to not hurry and get things right first time.
I think you are maybe too used to copy/paste or forked coins where the exchange can review the code and list the coin in a couple of weeks because it is no different than 100's of other coins which they have already looked at. BTR is a completely new codebase written in C# - as an example of the potential of the coin imagine how much of a bigger development community that opens the code up to than C++...
