We have been working with Odoo for a while ourselves, also we are helping our partners to work with Odoo, that is why for it is so important to know about your future vision for Odoo v10.
1. What is the future of the community Edition in V10? will the core be updated for community edition as well as for the enterprise edition?
2. we have been building lots of improvement for Odoo and we are thinking of selling our services to our partners, will we be able to keep selling improvements made for Odoo community edition in V10?
I've been at Odoo yesterday and asked some of these questions too. The conclusion is that they don't really have a good, solid, plan ahead. So I guess we'll need to wait to find those things out..
One thing was sure though: they will keep working with both a community and enterprise version.
