Depends on the product, not necessarily. The Essential Kit now comes with the expansions when you purchase it at no additional price (you do have to manually add it into your game however in the add ons). If it is a separate product like the ones Paul-A mentioned, those will probably be a paid add-on however as they are not expansions to a existing module. Saying that... I could be wrong as they make you re-buy Lost Mines of Phandelver to get Phandelver and Below Shattered Obelisk, instead of a smaller fee to upgrade, a discounted rate for owning LMOP, or include for free to anyone whom purchased LMOP. Aikepah said: Since that was a WotC/dndbeyond exclusive for buying the new Faerun books on dndbeyond I doubt Roll20 has much control over bringing it over. It would probably depend on if WotC decides to sell them as a standalone product or not. But you never know! For example with the Essentials Kit, WotC released some expansions to Dragon of Icespire Peak for free to anyone that bought the physical Essentials Kit, and then as a paid standalone (Storm Lord's Wrath, Sleeping Dragon's Wake, and Divine Contention). And then at some point they allowed it to be sold on 3rd party VTT platforms like Roll20. So its not unprecedented for these types of things to make their way to Roll20, we just have to wait and see if WotC allows it (and it likely would be a paid add-on)
