My biggest fear over it being made by Bethesda is that it's going to be a repeat of Oblivion. A game that should have had tons of replay value had absolutely none for me.
for me it had some replay value, i made three characters to get the achievements for it
i got screwed out of one due to a glitch that skipped one of my Mage's Guild ranks. so my main concerns are:
- better 360 achievements, as opposed to all "reach *rank* in *Guild*". they can have the storyline ones, but add some more interesting ones... like "Use VATS to score a critical headshot kill", "Steal from X people", or something like that. achievements for getting addicted to certain things would be funny. and maybe some Mass Effect style achievements that modify future characters to give replay value.
- less stupid bugs. Oblivion was FULL of them. i've had to reload games because some NPCs wouldn't spawn.
- oh and separate save slots for each character. another biggie for alt-whores like me
