CBDT in a statement said that persons having salary & interest income only being less than 500000/-, will not be liable to file ITR from AY 2011-12. Actual notification is yet to be issued. It is expected sometimes during this month end.
Now consider your brother's case : If your calculation suggests that there is no additional tax payable or refundable & he is having only salary & interest income then, you can wait till next month & actually ignore the filing of ITR, upon issuance of notification by IT deptt.
However, there are many more financial transactions, for which you need copy of ITR, such as apply for credit card, loan etc. So its advisable to file the ITR for your betterment & to maintain the continuity of records, if you have been filing the ITR in earlier years.
