For me it is quite obvious that it's Nintendo.
Sony is in a steady good pace that independent of E3 as far as we can see.
MS won't improve much doesn't matter what they show on E3.
Nintendo is early in the gen, have a lot of potential sales, and great IPs that are to make the first show on Switch and all that could drive sales a lot.
For those reason this E3 have more importance for Nintendo than to the other 3.
