That's the hope and I also will wait at least 1 of not 4 more month to actually see what has changed. However, one can see that there is a clear difference in what was promised during the elections and what was brought to action right now. Die hard modi or BJP supporters will generously look beyond these things now, but if you actually want to see the differences, you have to see what really was done, what simply was taken over and what might be just reactions of policies of the former government.
The budget was an important milestone here, since it showed (at least hinted) what the new government has in mind for the short term. And without many real changes, there might not be that many differences coming in the next 4 month either, not to mention that we soon will see elections again and we already can see policies changing, being delayed or even scrapped, just to look better before the elections, which isn't that good for the nation and fast changes either.
The big issue however remains inflation and there must be some changes for India within the first 6 month!
