The focus right now is on getting a new stable Linux version out and this is made simpler by focusing on 64-bit, which is what the majority of Linux users run these days (we can see this from various distro stats and our own download numbers for Opera 12).
I posted this elsewhere in the forum but I will repeat it here:
In addition pretty much all PCs, notebooks and even (non-ARM-based) netbooks from the last 5 years can be run in 64-bit and indeed, many of the users who run 32-Bit Linux could and (probably should) have selected a 64-Bit install of their distro.
This is not to say that there are no users who run a 32-bit version of Linux but if we tried to cater for all architectures, distros and package types right off the bat we would have taken longer to get where we are today and Linux users had been waiting quite long enough. I don't think it would have been wise (or fair to the majority), to have taken any longer.
I hope we can shift some focus to 32-Bit Linux but I am not going to over promise. This will not be a priority in the short term. We need to get out a stable (64) build and ensure we can support it adequately going forward. Then, we will see.
If you want to follow our development, you should check out our blog. If we start making 32-bit builds available, they will appear here first.
