I don't think Ericsson is going to drive any more in GP2. So it is F1 now or never for him. Or some other series from now on, like sportscars.
So in a Lotus-Caterham merge all drivers will come from the "Lotus" part it seems - Maldonado and Grosjean. Van der Garde's and Pic's F1 careers would be over.
Sauber-Marussia merge makes less sense to me, and as mentioned in previous thread, already from logistical point of view as Sauber is located in Switzerland.
Although, ironically, this is how Sirotkin could get a place at "Saurussia". So far the Sirotkins Russian partners haven't come up with money. But Marussia is also from Russia though they haven't shown any sign in investing in Russian drivers so far, at least not in terms of F1 seats.
