For what it's worth, Rebirth is an amazing game that I would honestly consider to be the gold star of anyone making a AAA experience today. If the goal is truly quality, I don't think it's feasible to try to make every game better than Rebirth given the breadth of content in it and its overall production quality.

Really what this announcement boils down to is that they won't be making more games like Harvestella, Valkyrie Elysium, Diofield Chronicle, and Foamstars, and they aren't keen on keeping things platform-exclusive anymore. And maybe they'll also be a bit more mindful of the budgets of their AAA games like Rebirth instead of taking the "spared no expense" mindset like they have been, which could come at the cost of quality, but I hope that's not the case.
