I'm not giving up on this Sonic, I'm just going to take a little longer than I thought I would. I don't see any real NEED for Sonic to be released this month just because people are hyped over it.
Not to mention I didn't even talk about what I wanted to give him, and I'm not going to talk about it either, as I want it to be private for now. Don't tell me it just "doesn't matters" or that "it's good enough" as you don't even know what I had intended, and by following your logic, I could just have released Chuckles in the past Christmas, thus making him lack things such as the new artworks I drew for him. So in short, no, I'm not going to release Sonic just with the default sprites changed. I want him to be released only when I feel it's ready, not when other people feel it's good enough.
Besides, I wasn't even supposed to be working on him right now. It was even a wonder that I could make this much progress on him recently without upsetting any of my commissioners. I'm already way too busy right now.
