Why hasn't SEGA donné plus attention to Blaze?

Blaze is a rather populaire character across the Sonic fandom. Granted, she's not as populaire as Sonic ou Shadow, but she has a sizable, devoted fanbase. So, why has SEGA neglected her? They've bastardized the supporting cast at large, but Blaze has received even worse treatment, reflected in a lack of merchandise (i.e. plushies, action figures, etc.) So far, I've seen exactly two official action figures, but what is most irritating is a complete lack of an official plushie. Hell, I've even seen Silver plushies, but so far, not one Blaze plushie that wasn't made par fans, and Blaze has been around longer than Silver. Sonic Team could do so much plus with Blaze. She even has an entire dimension to explore, of which I'm certain we've seen only a small portion of in Sonic Rush Adventure. This neglect would be understandable if she wasn't populaire ou was hated, like Big, but I've even seen die-hard Classic fans who liked her. Why is SEGA neglecting Blaze, and for that matter, the entire cast sans Sonic and Eggman? Sonic Boom seems to be a welcome change, but that game is a spin-off set in an entirely different universe. We haven't had a main game with characters other than Sonic playable since Sonic Rush Adventure. Is SEGA really so scared they might piss off the "ONLY SONIC AND EGGMAN!" fans?
