The Fabric of India that starts next autumn.
If you cannot make it to London there is a blog about the exhibition on the V&A website, where you can read all about it.
Speaking of Indian textiles. I have to point out this book, Indian Textiles: The Karun Thakar Collection, which I discovered last summer on the Style Court blog by Courtney Barnes (if textiles are your passion her blog is a wonderful read. In fact, I just noticed that earlier this month she blogged about the same exhibition). I haven't had the chance to browse through the book, yet, but I have a good feeling about it and immediately added it to my wish list.
