The Unicode Consortium (yes, there's a consortium, and yes, you can join for $75 a year) is thinking about what emoji should be added in 2015.
Taco and burrito emojis are cool and all, but I'm most excited about the popcorn emoji. I feel like we GTers would get some good mileage out of that. Also, the rolling eye face.
For the complete list of potential new emoji, check out the official list at the Unicode Consortium's blog.
