One last word from me.
I understand your stress ... been there, done that. One lesson I've learned is that, adjusting and living through the uncertainty of change in an organization is what makes many succeed.

It sounds to me like, the organization you're working for is exactly going through that incertainly of change. It creates a tremendous amount of financial stress, personnel changes, and it certainly is uncertain if the changes they are making will produce results at the end. BUT, they are certainly trying by taking the risk of introducing new products to the market. That means to me they are still in the battlefield, and for those who stick around the victory will be shared. I would stick around if you think you have what it takes to live in an uncertain future. I think the pay-off, (regardless of the outcome for the company), will be to your benefit. This is why:

1- If the company doesn't make it, you will have accrued senority, and that give you a more solid resume. Plus being aligible for some financial benefits.

2- If the company makes it, your logalty will be recognized for sticking to them even at difficult times.

You are at a win-win situation, IF you have the tolerance to deal with the uncertainly of change.

Good luck
