First, the great news, Minecraft Forge is a growing project that now has inside both Eloraam, Alblaka and SpaceToad among others, meaning we can expect much greater compatibility between their mods in the future, and the even greater news is that we can expect much less pixel-intensive version of Industrialcraft as a side effect.
Second, the upcoming new update to Eloraam's mods, aside from glowing blocks, is this:
Yeah, that is Eloraam's work: we can see both some lights and the option of putting the logic gates in walls or in the ceiling. Also, she has promised a screwdriver for some use with the plates (and that we will be ablo to put the plates by themselves, so covering logic gates will become possible).
Now for Industrialcraft, I'll advice you to go to Industrialcraft's blog and check. Can't say anymore here.
And finally for Buildcraft, the upcoming changes are avaiable as a beta in the mod's forum page, with the advice of only using them for testing without any other mods (because it might get unstable). SpaceToad made a video of the upcoming Buildcraft 2.0:
In short: A new liquid (oil), a new tool (the wrench, which is used among other things to change the pipe's settings, like which exit the items can use in a steel pipe), and a new mechanic for all the actually redstone-powered pipes and machines: they will now require engines, that are activated by redstone and come in three speeds: wood, stone and iron (each one is quicker than the previous). While all engines require a redstone source to start working (and that can be a continuous source, like a lever or a redstone torch), stone engines also require something to burn (like coal), and iron engines require oil (and they need a lot of oil buckets to get filled). See the video for more info on that.
