>I don't believe it offers most of those services
Incorrect.
>overdrafts in the UK are being restricted so be much less profitable
Incorrect, the fees are being regulated to ensure they're reasonable and customers are not being taken advantage of. There is still room to make a profit (and as the article says, they are per customer).
>I believe one of its sell points is no commission on foreign currency
I mentioned commission in relation to the marketplace concept, I am unsure why you are discussing foreign currency, it's irrelevant to the point I made.
>So are they planning on launching (their own) savings, or insurance?
They already offer savings accounts via multiple partner organisations. Unsure why you have such a fixation on bringing this entirely in house -- the bank still profits from customers using these partnered services.
Since the beginning the company has been pretty transparent and clear in that the idea is to build the best current account and make use of other providers as appropriate.
