Did I miss an annoucement or something?
Just make certain they're all coded to expire, not auto-renew.
I notice that when I look at the details of these .info domains it says "This Domain is registered at: Sipence, Inc." - I've never heard of that company before.
I'd recommend not renewing anything unless you are convinced the .info domain has actual market value.
However, if you have built an actual site on the corresponding .com domain, you should also consider the question of whether you would mind having someone else register the .info domain after they spot it in the "drop" lists.
