Conspiracy theories where there are none. Alright, I'll let the cat out of the bag.
Cosina is secretly trying to develop a new 35 f/1.1. (really it's 1.09777) they've got prototypes out - around 5 of them, but they're designing various hoods that don't obstruct the viewfinder anymore than current ones. I've seen the SC version - this will be HUGE in the japanese market. The MC version is expected to be a big seller with M8 and M9 and M9.2 (soon to be announced) owners.
Cosina is also developing a new 50 f/1.4 asph to compete with Leica's offering and it's supposed to be around the $799 price point. The prototypes I've seen are very similar looking in size and weight to the 50 summilux.
FYI, I've never signed an NDA so I can share what I know.
