If you do really need a laptop in one month and you feel that you are "wasting" your time waiting, the suggestion is to buy one and spend your time using it.
The MBP (or whatever) "Perfect Edition" will never come out. Every laptop in the world is a compromise and Apple's direction with the design of the MBP is clear, the advantages and drawbacks alike are known and if that's not your cup of tea just look elsewhere. Good alternatives exist, but laptops completely free of problems don't.
As for the thermal issues, I think you are overthinking it, really. They are probably serious enough on the i9, but the base 2.2 i7 will run just fine.
