1. Annihilationism will increase, as will support for universalism.I see multiple topics seething in the background but they are less likely to be explosive; atonement, evolution and maybe even a little something call gay rights.
With the rise of ReThinking Hell and the increasing atmosphere of openness (given the Rob Bell fiasco awhile ago), we will see more open support for annihilationism. Given that Preston Sprinkle of Erasing Hell fame now leans towards annihilationism or conditional immortali, this trend is indeed a hot one. Bad pun intended. You have other scholars like David Instone-Brewer, John Stackhouse and even Justin Brierley throwing their hats in the ring. Within the near future, the traditional view will die down and the debate will shift between annihilationism and universalism, with annihilationism becoming the dominant view.
Due in large part to the scholarship of varying egalitarian heavyweights (Philip B. Payne being one), I believe that the equality of women and men in ministry will begin to be sorted out in my generation. Thanks to the continuous remarks of many Complementarians such as Mark Driscoll and John Piper (both whom don't speak for many of my Complementarian brothers and sisters), the trend within evangelicalism is to reassess the traditional standing. Simply put, Christians are beginning to stop and stare and think about this issue. Many who are involved in justice are sensing something amiss, as well as many seminaries doing the same. The tides are changing, both at Talbot and at seminaries across the United States.
3. The battle for the Bible.
Inerrancy has been a hot topic since the 50s, but I suspect that the liberal/fundamentalist divide will begin to widen with more moderate scholarship and attitudes prevailing. Given the aforementioned emphasis on justice, I see many within my generation being repulsed by both the right and the left. This is a tendency to be sure, but I think one could mine for the best of both sides and create something new. We are currently within a giant hole left by the emergent church and the collapsing nature of fundamentalism.
