In response to further fan questioning, the age-old level cap discussion was brought to light again last week on the Battle.net board. While Bashiok's lengthy replies did not necessarily give us any new information, per se, he did give us very thorough explanations of what the team was thinking when it set the level sixty cap on Diablo III characters and how this will logically factor in to expansions in the future.

Diablo III Season 38 launched with Ethereals back, but players are reporting Error 395002, disconnects, and server trouble.

Blizzard reveals plans to speed up Diablo releases with more frequent expansions and updates as the franchise moves toward a live-service future.
All I want is a physical disc release of remastered D2 that doesn't require online check-ins.
I've lost complete interest. Too much FOMO with seasons as it is, now it's expansions? No thanks.
Why? Because most RPGs have level caps, it's never fun but them's the facts
Well Diablo 3 wouldn't be any fun without a level cap. Although if they succed to develop a RPG game that will have non stop update model such as World of Warcraft as MMORPG has, it will be pro.
Well lets say there is no level cap. Diablo would be awesome because player with higher level is the best. It is simple, there is no item level, some imaginary score (DKP,etc), there is level.
True that although there must be a level cap although if they keep with bringing high level content, the level cap doesn't matter at all. In my opinion, level cap only matters to seriously CAP other things such as DMG meters, Item Caps, Spell Caps and Builds.
I cant see people reaching it on their first playthroughs, so this is a way to get in re-playability. Especially if you play each of the classes.
