Is electrum 2 using bip32
Yes.
39?
No.
Even if they chose to use both bip32 & bip39, that would not be sufficient to guarantee mnemonic interoperability. I said something fairly bone-headed above:
(and many other wallets I hope) will be interoperable and support BIP39 in the not-very-distant future.
I don't know what I was thinking.... Even if wallets supported bip39+bip32+bip44, it would be close but it still wouldn't be quite enough to guarantee a mnemonic could be moved easily from one wallet software to another.
