Seriously.... if I was a major shareholder in Apple, I'd actually want them to deliberate whether Intel chips still were the best choice. Especially if the conclusion was, repeatedly, that they were. These decisions need to be reviewed regularly. Otherwise you got locked into a "because we always did it that way" mentally. And it keeps your suppliers sharp if they know you aren't permanently locked into their solutions. "Deliberate" simply means they reviewed the pros and cons. It absolutely does not mean that they are necessarily taking any action.
That's it.
The question would have been asked - what can we can, and what do we lose?
The gains are simply not enough to justify the massive loss of all the existing x86 software out there.
Running intel binaries at native speed is a massive advantage.
