I'm glad to see more of the Season 1 veterans back on Sesame Street (especially Big Bird, Bert, and Ernie). Giving Big Bird a specialty, though, doesn't fit the way he's been used all these years: even after the format change, he's remained a Renaissance bird who'll teach about any kid-friendly subject he's interested in. There is more to reading than identifying letters (the sponsor segments) or sounding out parts (the Two-Headed Monster clips)--but making an established character the main reading teacher seems as one-dimensional as relegating Cookie Monster to the "letter of the day" teacher.
