The Yoshi series is such an anomaly in the Nintendo catalogue - everyone complains about there being no new Wario Land games, but that's way better than being stuck in eternal limbo between mediocre and decent like Yoshi is. Not counting puzzle games, there are literally only two truly good Yoshi games (SMW2 and Woolly World - and even then SMW2 is the only one that compares to other Nintendo hits), which is a right shame given Yoshi has such a unique world and playstyle. At least Sonic still gets good games every now and then, and his bad games are easy to make a mockery out of - Yoshi is simply doomed to mediocrity, and he deserves much better.
And the classic design, as we know it, feels like it was only really used in Generations, Forces and Mania
