I highly doubt that they are actually trying to discover anything which will be better than the DLS system. And as long as there is not much protesting or anything made against the DLS system, ICC is not even going to improve that system either. And the one thing people have to realize is that when the DLS method was introduced it was very good for that time. But time has changed and the system also needs to be upgraded.
If someone personally or any institute or their students doing anything for this then surely no one can give updates because this will come when they will launch this all and if we expect from ICC then I am sure it's 100% they are doing nothing about this because they have no enough time for this all.
DRS is surely a good idea and nothing complicated happening with this all even we still need few things to implement in this technology era, but these all depend on approval from BCCI which is currently controlling all main points for this sports authority as they are currently not implementing any technology related thing in their domestic set up even they are most rich in cricket world due to expenses so how can we expect more changes and thing related to cricket can part of this without their approval as they are now looking for just own profit.
The BCCI is controlling the most important part of cricket, the ICC. But before when BCCI said that they don’t want to implement new technology, it was understandable. Because they didn’t have a good grasp and control over ICC.
But now they basically know almost everything that the ICC is doing.
So, now they should not have any problems accepting the new technology. So I don’t see why they are going to oppose this idea. But that’s after something actually develops. And I don’t think there is anything being developed by the ICC in this DRS matter.
For me, DRS is quite simple but the problem is it does not take into account some important matters. If they somehow are able to implement those into the DRS system, I don’t think anyone will have any problems with the system anymore.
