I was following this forum and Track It forum to understand the progress of the Tier 1 Extension application. I am not sure where I read that if you write email asking your progress to UKBA, they might revert back.
I did that and received the following response:
I did my Biometric on 12th April , 2 dependents and Salaried (UK + India). Based on the above reply, will it be possible to confirm that it was a success.Thank you. We can confirm that your case has been decided and that you should receive your decision letter, BRP and original documentation soon.
Appointment Exceptions
I am not sure whether they send BRP to the failed applicants as well. I hope my case is not in that category.
Waiting for your expert opinion.
