It's still very early days, I think there's a bit of re-jigging to schedules to be had. EasyJet are probably just putting flights on sale to get early bookings and haven't really got a realistic flying schedule together yet.
I wouldn't rely too heavily on how many gaps or how long the gaps are to try and guess potential new routes. Any gaps or anmolies at the moment will probably be sorted in due course by re-jigging the shedules. That said, I'm not completely ruling out any hope for new flights/routes. I'm sure it would be very welcomed news if they were to add something new!
