I would like to know if the ICC is considering other predictive methods than orthodox Duckworth-Lewis to arrive at a result in an interrupted cricket match?
There are not any current news for this; you will find some references like this one, but the case is that these are not yet officially quoted by ICC so it is hard to believe such stuff.
Also here is a news article which says they are continuing with DL.
Well in the race of other methods the one which is considered was VJD method.
But as noted in Wikipedia, the ICC still uses the Duckworth-Lewis method in all international matches. The Jayadevan system has been put before the ICC in the past, but the decision was made to retain the Duckworth-Lewis method. The ICC will address the issue again at its next meeting in Dubai.
