Hobbits: Yeah, yeah, yeah. We have halflings. But halflings in 4e are more like 2e Kender, without any of the fun (or "infuriating", depending on whether you're playign the kender, or someone else is). I want to see hairy-footed, pipe-smoking, anti-magic hobbits. I'm sure I'm not alone.
Ok, so its not a WOTC release, but it is authored by a certain undead rodent...
Advanced Players Guide has "Shire Halflings" which might be to your taste. They are in the free preview here.
