They'e effectively equivalent in most contexts. In another thread I was gently (but politely, of course) slapped down for suggesting that there might be a detectable difference.
A general wish for the future needs only the present tense. But there's a case for using a will-future when there's a specific time in mind:
A: I'm thinking of stopping over in Japan when I fly back from Sydney to London this summer.
B Oh, I hope you will come.
But the present is OK there too, and B could add emphasis by using 'do' instead of 'will'.
