RC-6 Wireless Remote being replaced by Canon?

Hi all,
I was just looking to check some details on the RC-6 to see if it suits my needs for my 5dMkIII & I found most details have been removed & it's listed as 'out of stock' with both Canon Australia (my local page) and Canon USA.
Obviously I don't want to spend the money on one if it's about to be replaced by a model with better functionality etc.
I know they're only cheap in the US, $15 to $20, but we get ripped-off by Canon in Aus so they are 40 to 50 bucks here... I can think of much better things to spend that much money on than a redundant remote.
Anyone heard anything about a replacement?
 
Couple years ago I bought one and it just quit after about 6 months - battery change made no difference. I was willing to try again, but they have been unavailable from Canon for over a year I think.
Just tried a couple days ago, somehow I ended up with a $30 credit at the Canon store, and there's nothing else I'm interested in.
Maybe I'll grab a battery.
