Nothing will happen. There will again a propaganda spreading rumors that this will happen, that will happen blah blah blah and people will be occupied guessing things. This has become a norm. Their CEO said in July 2013 that MPEG4 Migration will be complEted by July 2014 and he has failed to comply by it, same happened to other rumors like sat migration or GSAT10.
The reality is that Tata Sky does not want to increase bandwidth or channels an they will just keep giving excuses, fans/stooges will keep protecting/promoting Tata Sky and even 2020 will come.
I request u all to focus on ur life, don't expect anything from Tata Sky. If u r unsatisfied just dump them and opt for Dish TV
