Are shards and roll ups the same thing? I can understand roll ups means publishing to the L1 block chain - but do shards necessarily need that? I’m comparing to shards in regular dbs- the only time you need dist txn is if you cross shard boundaries, but if you can guarantee locality, it is avoidable.

They’re not the same, but effectually have the same outcome — the current shard proposal has receipts landing on the beacon chain so that they can be used for cross-shard transactions. Guaranteed locality grows implausible as the number of shards increases.

Thanks for sharing. 

Are there any proposals to reduce the 12s time? It seems like a big lever.

Vitalik has explicitly argued against doing this, as it would result in the network becoming more centralized: https://www.reddit.com/r/ethereum/comments/slzfsd/why_wouldnt_proof_of_stake_drastically_reduce/hvu9ekc/

Thank you so much for sharing all of this, I learned a tonne of new stuff today. 

The lower latency connections that Vitalik refers to kinda reminds me of arbitrage techniques in low latency high frequency trading.
