So, they'll all have to be replaced in about 6 months time - what's the
likelihood of the new company running that franchise keeping the Connex
name?

About the same likelihood as your local Tesco supermarket closing down
and a new company moving in - but carrying on trading as Tesco.

Connex is the name of the company operating the franchise - and they are
a worldwide transportation company.

(It's different for Thameslink though, as that name is owned by the SRA
- so no matter who operates the service, it's still likely to be called
Thameslink.)
