That's pretty much what I would expect to hear.Thank you all for clearing up my question.
I am wondering if I got the points right.
Are the sentences below likely to be heard in everyday English?
Did you hear that? Bluetooth 3.0 (three point oh) will be coming out soon.

Thank you all of you indeed again.
