I don't expect them to take place until the competition makes significant and consistent market gains against Canon. It's a mistake to think of the DSLR business as anything other than a business.
I'll agree with the second sentence but not the first. After all, isn't it better to make the changes before losing market share rather than after? Mismanaging major technological transitions drove Kodak into bankruptcy.
The managements of Olympus, Panasonic, Sony, Fuji and Samsung all decided, more or less simultaneously, that the case for MILCs over DSLRs was compelling enough to make major investments to overcome serious barriers to entry,
the biggest of which seems to be getting stores to carry not-Canon/not-Nikon cameras so that consumers can look at them and buy them. It very much remains to be seen whether Canon and Nikon can leverage their installed base and very extensive DSLR lens lineups in the transition to MILCs.
