Hey sandhu100,
it is probably good news indeed, congratulations!
How long to wait - that's difficult to know! depends on when you sent your application, when you got approved as a sponsor etc - if you share your timeline, somebody might be able to give you a little more indications, but of course - only CIC really knows when the visa will be issued. But New Delhi is a fast VO so you should be not too far from the end!
Good luck,
Sweden
