Just to expand on what Rich said: we try to build products that solve people's problems. We're very focused on making sure additional features solve a lot of people's problems (our feedback forum helps us figure this out: feedback.uservoice.com/forums/1-general-feedback), not just single clients (even if they have a lot of money). It's a lesson we've learned (painfully) several times. So we tend to make our own schedule and try to delight customers with the things we add, rather than rush to keep up with things potential customers have on their shopping list.
