All ... additional 3D titles will be coming ... not sure exactly when ... after a break for awhile we are back into getting a few more done ... there's not really any backstory on these ... PPS have all 8 titles in stock and available.
Also, as for 3rd party licenses, the issue is not what was just stated, it's just the costs and overhead of dealing with a major licensor (studio) that makes them less interesting ... they don't really care where a translite goes ... licensors don't just license one item, they have a upfront fee which is usually in the $5K-$25K range and so long as they would be pinball (vs coffee cups or t-shirts) items in fact I'm sure they would prefer that more are sold which generate more royalties for them.
Stay Tuned ...
