The three games you named are all great choices, although I think you could substitute in Banjo-Kazooie for Fable and still be right.
@FishyJoe: if you mean in general, then X-Seed and Capcom are both supposed to have some sweet and unexpected games to unveil at E3. If you mean just by sales, then Allen Car's Easy Way to Stop Smoking or My Weight Loss Coach have a strong chance of footing the bill.
