Yeah I'm hoping for a 24mm 1.4 too or maybe a good zoom.
Just like the 35mm 1.4 where Canon had a great lens but maybe priced too high, there's probably a good opportunity for someone to sell a lot of lenses if they can make a good 24mm priced at < $900. With the 50mm being relatively good and affordable already, I would be less excited about that focal length update, but maybe an 85mm 1.4? Personally I'd like to see an optically superior and more affordable wide angle zoom like the 16-35 2.8 II, but that's just me.
Whatever it is, hope it's as good as the 35! I don't even really need that lens, but I want it now lol!
