So yeah, as correctly mentioned by Outbound the new form states that the Embassy/Consulate needs to send the form. So, depending on the Consulate you might/might not be lucky.
The Blocked Amount for 1 year expenses is currently 8640 Euros. Kotak Mahindra is a decent alternative. It is usually hassle free. (But not always. If you are in a hurry, then it is best to maintain regular contact with the person responsible.) If you deposit 9000 Euros and ask them to transfer the whole amount, then they will do so. But, They charge a higher rate while opening the account, while the rate is much lower when they are transferring the amount to Germany. The difference will be stored in your Kotak account here. The extra money is usually to cover the variable rates and international transfer fees. So nothing much to worry.
As soon as you land in Germany, after your City registration, you can directly go to a Deutsche Bank branch, open a student account and then share your account details with Kotak people. But, they will charge a Fees (was 150 Euros when I came) for blocking your amount. So, this is where the extra amount comes in handy. Else, you can always deposit the extra money.
Another alternative can be opening at the local Deutsche bank branch. But they usually ask for a deposit (~50 k to 1 lakh) in addition to the blocked amount.
So choose whichever is more convenient.
