I gotta admit I'm pretty curious about what they'll be releasing with it.
Perhaps a more productive approach to the matter of the future update would be to discuss the most preferred, if not the most likely, issues to be addressed in the next and successive updates. I see the following as being the most likely to be considered for, if not included in the next few updates:
Low-hanging fruit*recompiled game executable with optimization flags for increased PC performance (easy and obvious choice and embarrassing to ignore)
*item and perk fixes that address upgradability of items; missing entries in perks such as matching set; ebony blade behavior matches two-handed weapon classification, etc.
*fix mouse sensitivity in User Interface with regard to dialog choices to ensure that intended options are highlighted and chosen
More involved fixes*investigate savegame file bloating and possible connection to game instability (one of the few issues they've already said they're working on)
*numerous quest bugs (assumed to be an ongoing effort)
*address numerous problems in favorites/hotkey system linked to weapons being renamed, removed from favorites or having their hotkeys removed
Other, more specific issues including balance and exploits*inconsistent or inappropriate behavior of objects contained in player character residences (bookshelves, mannequins, etc.)
*balance Smithing by removing infinite "Legendary" status, i.e. there should only be one Legendary "tier"
*Fortify Restoration potions should not enhance Fortify enchantments (this fixes numerous exploits)
Edit: Note: these are not my personal preferences, only what I think will be most likely on the top of Bethesda's list given what they've provided in the (sparse) details of their Skyrim support roadmap, as well as being consistent with the types of issues they've addressed in updates so far.
