Joking aside, Hook had enough housing given planning permission to increase the population of the village by about 20%, which will need to be started in the next three years (only one of several sites is large enough to justify sales being spread over more than two years).
As such it could be possible for there to be something like an extra 150,000 to 200,000 yearly rail journeys from Hook (yes that is probably only about 35 London season tickets). It would also make rail travel more attractive as there would be direct services over most of the day to Winchester, Eastleigh and Southampton (which are rare at present) and 3tph to/from Basingstoke for much the day. As such it could attract more people to use the trains.
On season tickets, if it is possible to book a seat (which was mentioned up thread as a possibility) and so possibly being able to always use a laptop on the train, I can see a lot of people taking that option (even if they are limited to selected services) over the existing services. Especially if the journey time is slightly lower and the season ticket price had any form of reduction.
It sounds as though whatever happens, Hook could become a more important stop in the near future.
