AFAIK it has been hinted from a few sources that an update is being prepared and might be already in the internal/closed-beta stage.

And when you think about it, releasing another update might be the best you can do when you are in a crisis and need to secure more investment money & licensing partners/-s. It makes you product (Sailfish OS) better, more suitable for licensing and makes use of your existing (remaining) resources without having to shell out money to an external entity (as with shipping the remaining tablets).
