Perhaps if you read my other posts you might realize that I elected to use "A15 variant" because I got bored of writing "A15 class" every time. The fact that is isn't an Cortex A15 supports my thesis that Apple could have a 64 bit A7 before the rest of the industry have actual A50 implementations in 2014. Which you might have realized if you were reading for comprehension rather than reading for gotchas.
The real issue is whether Apple's team can get their new designs implemented on an annual release cycle...if they can then FIRST gets a $10 donation. If not, someone else does.
