I don't see 4J changing the way they have always approached Updates.
They always follow-up a new content release with bug fixes. Nothing different this time around.
I personally think the updates will continue to contain bits of 1.7 and 1.8.
I also think 4J will be steering clear of doing any type of massive update since the last massive update caused so many bugs
What does this even mean? Do you think 4J will opt instead to release, say, one biome/feature each update a few months apart, interspersed with bug fixes, all to avoid a "massive" update that may contain numerous bugs? That's not the most efficient method, IMO.
What I think...
Hmm. I think this last update, TU25, was a precursor to the update that actually gives the 1.7 biomes. Despite what some have said, tu25 actually had a lot of content, mostly aimed at map-making and Creative mode. I've secretly come to call it The Adventure Update. It also contained some significant changes to the main menu UI, which could be seen as a way to make it easier to implement changes later (like tabbing over from "local" games to "server" games, if that ever becomes an option).
I think the next Content update will bring the console to 1.7.x with some 1.8 features pulled forward. And Yes!, this is the same prediction I made prior to TU25, but I admittedly had much higher hopes. I'm really pleased that Written Books have made it to console, though, so this last update was worth the wait for me. If only it contained custom Spawner Blocks...
