For what I saw in the Minecraft forums, we can expect a 1.8.1 version for RedPower and Industrialcraft 2 (meaning a new version of Minecraft Forge, most likely), but I didn't found more mentions about other mods (I didn't checked them all, anyway). What is really important, however, is that unless the code related to the mods remain unchanged, there won't be much mod actualizations for a while, at least until the whole "adventure update" is released (yeah, Notch is releasing that update in minipatches).
In case you want to check the news, by the way, I found some tours made by Paulosoaresjr and updated to Youtube. Here you have them:
- Village monks, swamps and a little of snow biomes
- The update to the Nether
- Snow biomes, and a snow golem
I'll advice to subscribe to his channel, since about 13 hours ago only the first one was up (I'll live in GMT+1, so I was sleeping while he was uploading XD).
Have a nice weekend!
