100% agree with Camster- MBB will stay and go deeper and deeper into implementation (McK is already well on its way)- OW will stay because its revenues as only slightly smaller than Bain and, most importantly, it has the firepower of MMC, its Fortune 500 parent company, to grow via acquisitions- Roland Berger and AT Kearney will either merge with one another or a Big 4, but they will be gone by 2020 no matter whatSo we'll have an industry with ~8 players (MBB, OW, Big 4), which is about the right level of consolidation you want.When all is said and done, the days of "prestigious strategy MC" will be over.
