I hope people still talk in all their multitude of languages. Maybe we won't. Maybe we'll all have the gift of tongues. But I, for my part, would be delighted by the prospect of an N. T. Wrightish eternity to be spent, among an infinity of other things, learning every language. Ever. And just like the clothes in Narnia have no zippers or starch or elastic, we could learn without the need for prefixes and periphrastics and pluperfects.
I hope so.
