Only speculations are all around nobody knows exactly what name tag Sony will give to their next series camera after A7 series’. Yes, absolutely right as you read! Actually, a new rumor recently popped up over web describes that a new camera is on the way that features high burst rate and fast AF, but the rumor is way about from the confirmed information… As they are speculating it to be Sony A77III, but at the same the source behind this rumor clearly says that not A7 series then it will be very fair to expect it as Sony A9 (because the most popular name circulating on the web).
A new camera with very fast burst rate and AF speed, at least one telephoto lens, not the A7 series, not on CP+”
In the end, when we have no further side of the story or rumor then better will be to wait and wait until rumors get some reliable side.
