Markc, Honda does have plans in the works for a side by side but I doubt it would be anything of interest for hunters or mud riders. Seems like the entire company is leaning more toward a sporty utility ATV market.
Txmntman, the Warn 424 is not a locking differential. All this product does is allow you to un-lock the front end of a utility quad so you can have 2wd as well as 4wd. I think what you are thinking of is the Detroit Gearless Locker. From what I have heard about the DGL it is much easier to steer than a spool locker, but it also has to be re-built from time to time so it requires more maintenence.
I would highly suggest to anyone that decided to use a locker in the front end of a full time 4wd that they get a 424 so they can switch into 4wd because fully locked is hard to turn. The only problem that I have heard about with the 424 is that some people have had the handle slip and engage/disengage 4wd sometimes.
