Dont bet on it, Frostbite is actually a reasonably nice engine to work with, limitation wise, its all fairly extendable, the main issue is resolving the unknowns, and then writing tools to accommodate the end user, actually make it easy to mod, rather than having to require a degree in game design to know how to use the tools. Yes its going to take time, yes most of the scenes will be dead by then, but new games are always coming for me to work on (which i will continue to work on the older games as well). And if anything over the last couple of months, ive learnt that even a seemingly dead modding scene (eg. SWBF) can be reignited by the presence of decent tools.
