Might, might not - sounds like dieback, which sometimes happens. You may find they produce new stems, but make sure, if they do, that they're not from below ground, off the rootstock.

Thanks for the reply, I will just wait and see then?

Yep, that's all you can do I'm afraid.

Most suppliers of bare root roses will be sympathetic to your problem and may replace your dead ones. I would contact them. If you bought them and planted them right away they should not be looking dead already. Sounds as if they may have been on their way out before you bought them.
