It's good that you've acknowledged the file size as an issue and plan to address it quickly. To the players, that's a great sign that the devs are listening. :)
I think a lot of devs under-estimate the impact that large filesizes can make on an otherwise good game. I've found in the past that large downloads can deter potential players; heck, I've had people tell me a 200 MB game was too much of a hassle for them.
