Update : It seems Sony Ericsson India has avoided the delay in launch and Xperia Mini Pro is now available from Flipkart and Letsbuy for INR 15.5K . We have also heard about the in-store availability in some cities. 
Sony Ericsson has delayed the launch of Xperia Mini Pro in India. Smartphone was earlier scheduled to launch this week in the country. Flipkart has changed its pre-order listing to reflect that.
Company will now launch this Android QWERTY slider in the second week of August. It is expected to be priced at INR 15,090.
Hi Gaurav,
I know this phone has not been officially launched by Sony Ericsson, but it is already available at letsbuy.com.

On applying coupon code icicilb you get Rs. 1200 discount. So the final price is Rs. 14,199 !
Xperia mini pro Sk17i is available on the counter at sony ericsson exclusive mobile showrooms @ 16000 and you can bargain as well.
I tested the phone for 15 min and compared with old Xperia x10 mini also.
The keyboard mechanism is not robust and feels little shaky.
