Sennheiser promised this mic over 15 years ago when the 8000 series was released, to replace the MKH30.
It was then delayed, scrapped, rebearthed, scrapped again. 4-5 years ago there was an online poll by Sennheiser (probably the beancounter department) to see if there was intrest.
Now it will become reality (???) - and suddenly worldwide about 2,5K sound engineers will either buy 1 MKH8030, or - finally - buy into the series and get 4-6 mics.
IMO some beancounters will faint, and some will be fired instantly, because they have cost Sennheiser a lot of money during those 15 years.
If it is as durable and even better sounding then the MKH30, it will be the best (full-range) fig8 mic available.
