I can't see VIP removing flexible decisions from Vicky 2 and putting back hard-coded events that fire on a specific day and time. It'd kind of defeat the point.
Well in VIP for VR we are already moving towards at least having options for players to take in the events, and events which did not have options were being reworked to provide options, and going through the major events to get the triggers to be much more context sensitive than they were in earlier renditions Given another year or two, that process will be much further along, and more alternative lines of development will be possible. But it all takes time, lots of time, to do. And the V1 event system retains a lot of rigidity that makes it very difficult to fit the situation on the ground during gameplay with the intent of the events being scripted, meaning very cumbersome triggers and extensive event chains with more flags than in front of the UN General headquarters needed to keep things organized.
For V2, VIP will most likely have to reapproach its event system it has to make it do what posters like Orinsul say but also clearly keeping an eye on the gameplay environment that V2 creates, both for the human player and for AI nations. I believe can be done, BUT wil require a good amount of rethink as to how to frame the triggers so that the context in which the events fire make sense and the impact of the events are not so draconian as to overly constrain future player action down one specific path (or at least ensure an "out" option) or spring upon the player something game-ruining just because it happened in history even if you are playing your nation in a different way (would Garibaldi's Red Shirts have landed in Sicily if the Bourbon regime was a progressive con-mon with a strong industrial base, and more importantly, would the island of Sicily have risen in support of Garibaldi in that situation, or was Garibaldi's success due to the nature of the Bourbon regime and economic conditions of 1850s Sicily. Should Sardinia get a Garibaldi & Redshirts event if 2S is not in the condition it was historically, especially if either 2S or Sardinia is being played by the human in this situation?).
Basically it means that event writers will have to think more openly, they can not simply construct the event based on the historical events that did happen, but also really must consider contexts in which the historical event would not make sense at all and the ahistorical routes that could have evolved had the historical action in response to the situation not been taken.
That said, the event system in EU3-HoI3 based games is MUCH more flexible in terms of crafting events and event triggers, once you understand the system and where it differs from the old. For example, it does alllow much more precise trigger writing and targeted effects so that context makes better sense for an event to fire and the impact can be better targeted to fit the situation in game, rather than the all-or-nothing approach to events that the old game engine was based on.
Part of the problem here I think is that players are only thinking in terms of what the EU3 toolkit has available for modders, which is no longer the whole story in terms of modding in Paradox games. In addition to the major steps forward made by Paradox in the various EU3 expansions, which means modding in Heir to the Throne is much more developed than in base EU3 1.0, alos don't forget that in the interim Paradox has also made HoI3, and anyone who has done some investigation into the decision and event system for that game should know that the nature of event writing in the current generation games took a giant leap forward with the HoI3 toolkit. See the decision and event system used in HoI3 for better explanation here of what I mean, but HoI3 adds a hell of alot more tools for modders, tools which I would expect will be abailable in large part for V2.
As I've said previously, probably the vast majority of VIP events can be translated over in my opinion. Will take some time, and some tweaking for balance to fit the new game environment, but I'd definitely say it can be done, but with the understanding that the triggers and effects need to clearly fire in the right context - geopolitical, internal political and socioeconomic.
