Hopefully now Indian will be also skipped this tour because this is already rejected by ITF and its tribunal as well so if they will not tour then they will be going into Davis Cup group 2 and Pakistan will be stayed in this group as winner.

Well, India won't be touring to Pakistan to play any sports whether it be cricket or tennis. I do not know the influence of ITF, but if we talk about cricket then ICC will definitely favor India and they will try their best to host the tournaments outside Pakistan even those which were planned to be hosted by Pakistan. They would not want an India to miss out on any tournament only because they can't visit Pakistan, rather they will move the tournament outside Pakistan and if Pakistan does not want to play, it doesn't matter to them.
Last time, the Indian tennis team visited Pakistan was back in 1964 and they won the series too but since then a lot has changed and now Indians have become a mighty giant in terms of ownership and resources of ICC.
