Depends what you mean by Haskell 2. If it is an experimental language
that shares some superficial similarities with Haskell, sure we may
have Haskell 2. If you mean a serious successor of Haskell with the
expectation that many/most Haskell users will eventually move to
Haskell 2, then no. Haskell has been gaining a lot of momentum
recently. That's good and bad, but surely makes it hard to change the
trajectory. (This is, of course, just my personal opinion.)

As Lennart and Ganesh have argued, the amount of breaking changes that
we we will be able to fit in without causing serious problems is
