The Gibson TB-Plus pickups are machine wound. If they were MIC using identical materials and specs, would it matter? The automatic winding machine wouldn't know where it's located. Likewise for the upcoming Vintage PRO; what will matter is what they'll sound like. Good or bad, they won't sound any better if they were MIA with the same materials and specs.
Wood is a different mater. AFAIK no Asian instruments have ever claimed to use genuine mahogany. That's not to say that you would notice a tonal difference, you'd have to compare for yourself. OTOH Gibson has reportedly used plantation grown genuine (Honduras) mahogany from Fiji in all but a few Gibson Custom models since 2008. I doubt this wood is identical the same species harvested from Central and South American forests.
