If I purchase this bundle do I have access to the previously released journals or will I have to wait until this releases?

Can I assume from your question that you don't have 3.1? If so, I would recommend that you purchase it first (https://www.logos.com/product/147730/tjl-upgrade-bundle-31 ) and then wait for this pre-pub. Dynamic pricing will be applied.
...Or call FL to see which would present the best deal for you. To answer your question, I don't think you would have access until it ships. Neither will you be charged until then.
Pre-Pub is $100 cheaper or do I not understand how this works?
Normally, Bruce's idea is best. But you're right ... 3.1 is more than 4.1. The wait might be worth it, or call Logos to see if you can download already produced 4.1. Normally JT's point is operant ... wait, wait, wait.
