Imported edition of the book is available on Flipkart. In fact, Flipkart is showing that Indian edition is also coming.
I am also waiting for the hard print. Till now, one of my frnd bought the imported edition so borrowing the book sometimes.
I think, the question "SCJP 6 or OCPJP 7" is quite common among the ppl like us. I was also struggling with this question. At the end, I am preparing for OCPJP 7 since it is the most recent certification and I will be considered "most updated with the technology" after this certification.
Thanks Nancy for pointing this out. I am completely agree with you. In fact, K&B book is delayed for two more months and it will be available only in late June. So, OCPJP aspirants have only one strong alternative left i.e. the book by Ganesh and Sharma for the time being.
