Stay with Marketpress or move to WooCommerce

I've been a loyal WPMU Dev guy, contributor, bug finder and squasher...but I am having trouble with the development cycle and the communication with us the community.

I have clients that I feel I am putting on the hook...waiting for the results of the release. Currently there are basic feature holes in the Marketpress solution that are promised to be fixed...its been almost a year. Ability for multiple product variants, multiple product images, etc...i've even proposed solutions that could be made immediately. But if the development cycle will overwrite these solutions in the next update or has a different method than that presents a problem.

It would be good if there was a real timeline and what the expectations are of this release....right now I feel like we are in the dark and it is now time to move forward and be a bit more transparent on how to proceed.
