No they changed the Algo specifically to prevent asics from being able to mine it.
I agree with you about the Algo, and I think this is the part that I'm missing and confuse
I believe the Algo is managed by the software.
For example, PhoenixMiner 5.2 and older versions can't mine the new ETC algo, but the new ones over 5.3 no problem.
From a hardware point, there should be no difference between GPUs and Ant E3. They both are GPUs.
Please correct me if I'm wrong.
By the way, Ant E3 was the most profitable asic miner ever. More than 2 years and a half and still profitable. Is unbelievable. And I'm sure E3 can continue to work fine, but I don't believe bitmain will release new firmware
Hope someone will found a way to patch the software

No th eminer in this case is simply feeding the asic. The mining is hardwired into the asic chips. No changes.
