1/9: I've been absorbed reading through the v2 vault code from @iearnfinance (and asking @fubuloubu a bunch of questions), and I'm more impressed (and eager for the release) the deeper I dive. 
2/9: The v2 vaults are no longer limited to a single strategy - they can have as many strategies as can be designed. This is important for significant AUM, as profitable yield generation is a very different matter with $1k vs $100 million.
3/9: Don't worry about which strategy received your funds. Deposit into the vault and get your vault shares - the vault deploys your funds to the strategies best poised to maximize gains. You collect your portion of the yield generated across *all* of the vault's strategies.
4/9: This means your funds aren't sitting in just one strategy, you're getting the combined might of every strategy that comes out of yearn's community for your asset. Nor does a v2 vault have to worry about being flooded with capital, unable to safely generate yield.
5/9: The v2 vault is smart. When a user withdraws, if there are no funds sitting undeployed in the vault, it withdraws funds from strategies in the order of least impact. Funds are taken from the strategy that will disturb everyone's gains the least (then the next least, etc.)
6/9: The v2 vaults are also fine-tuned. Just going straight to the highest yield leads to high risks for your assets, that's why yearn's v2 vaults pursue the highest, risk-adjusted yield. Managing risk is critical, and the community parameterizes vaults to balance risk vs. yield.
7/9: The v2 vault has an emergency shutdown. This will recall deployed funds as quickly as is practical, minimizing loss. Deposits are halted, new strategies can't be added, and each strategy exits with minimum damage to position. Users can of course withdraw without restriction.
8/9: Of course, this means the strategy has to account for this, which is why the v2 vaults have a BaseStrategy that all v2 strategies must be derived from, providing a leg up for the yearn community to start cranking out strategies and bringing you yield!
