Yaron Zelikha, an economist and formerly the MoF Accountant General, just announced he is forming a party. he says everyone wants to be Prime Minister, he just wants to be Finance Minister. he claims Israel is on its way to financial ruin and he knows what needs to be done to save it and that plan with him as Finance Minister will be a condition of his for joining any government.

Ofer Shelach formed a party. I don't know what their goals are. It might also have to do with finances, based on the context of his party when he formed it.

Gantz's party is falling apart.

Ron Huldai is forming a party. he says he can save Israel from internal combustion.

It seems to me like Zeleikha's and Shelach's parties should merge. 

Gantz should join up with either Huldai or Yesh Atid. Both are difficult moves. Lapid won't make Gantz #1 again in a joint party, so Gantz would have to be willing to sit under Lapid.  Joining Huldai presents the problem of Avi Nissenkorn being Huldai's #2. Menaing Gantz would likely have to be behind Nissenkorn, after both of them being in Kachol Lavan with Nissenkorn behind Gantz. Gantz really doesn't have any good moves, but those are the parties that seem best suited for him to merge with. if he doesn't he will be lacking any influence, at best, if he even passes the threshhold.

It is going to be a weird election season, with a fractious left, a fractious right, and some parties that nobody really knows what they are.
