If it is, they'd better go the Yoshi's Island route and not the Yoshi's Story route. --- My name is Mottman, and I approve this message. "Champions don't whine, they win!" - Vangarre from Xenoblade Chronicles
There's been tons of rumors about a return to Yoshi's series for a while, particularly Retro developing it. I never played a Yoshi game before, but it seems like wasted talent to have Retro develop it. I mean, I'm sure Yoshi is awesome, but what I've seen from Metroid Prime, Retro is filled of great writers and I wouldn't expect a Yoshi game to have or need a good story, or a story at all.
