Marketpress 3.0 (2.9?) ETA & Combo plugin

Hello y'all,

Back when I posted my 'per-item coupons' hack, Patrick mentioned that you're working on adding additional coupon functionality to Marketpress.(https://premium.wpmudev.org/forums/topic/marketpress-per-item-coupons-beta)

So, I'm contemplating writing a quick plugin to offer combo/pack functionality (after buying several from Newegg.com over the holidays). But if the coupon functionality is changing, I'd love to work with the new core version rather than my hack. Any idea when we might get a beta of whatever version that is? (2.9 or 3.0?)

So I guess I have two questions:
> Anyone interested in a combo items plugin?
> ETA for a 3.0 (2.9?) beta with new coupon features?

Thanks!
