I think the obsession over tiny minute details over laptops are a bit ridiculous.
The laptop as a whole hasn't really changed significantly since...they were first released. And whatever power increase there will be if any within the next year will be so negligible for 99% of workflows that there's no point in obsessing. Of course if you wait 2-3 years then it gets more substantial.
You buy based on what you need right now. The next thing coming out is not going to improve what you're doing by any real measurable amount.
