I'm pessimistic, personally.
Nathaniel was one of my favourite characters, just because he wasn't a goody-goody do-no-evil protagonist, but was on the 'evil' side, so to speak. It made it interesting for me.
Without him, the book would loose a lot of it's appeal. Also, Bartimaeus' footnotes keep the book fresh, however I feel they will begin to wear thin after a fourth book, and near the end of the third I was beginning to get disgruntled by his static personality.
The book will probably follow in Kitty's footsteps some amount of years after the British Empire has fallen, or at least have a PoV of her in it - to connect the stories together without being woven together like the original trilogy. I don't mind Kitty, but she's not the most interesting character in the world, and it would personally not make up to the first series IMO. Although I am curious to see the progress Britain has made and see how the world is under the American 'Empire'. It will probably introduce a range of characters along the way though, which could go either way. And Stroud will have to come up with a completely separate conflict though - I hate when all things are tied off, and author comes up with another conflict just to make the series continue. It's irritating, personally.
I personally don't see much potential for another series in another time-line - it seems like milking an idea to an extent, and I wouldn't be that interested if the only consistent character was Barty. If it were, it would likely not be Egyptian, but somethign separate. I don't really want to get to know and like
another set of characters all over again, I'd rather stick with the remains that we know, and add to them. Characters are tricky things - they can often turn out unintentionally badly, and I'd rather not risk another set of them as there are more likely to be unlike-able ones, and I'll be constantly comparing protagonists and antagonists from the first series to the next series/book. He'll also have to avoid the trap of a formulaic set-up. Although part of me thinks this is exactly what he is planning, hence the pessimism.
If he tries to revive Nathaniel though, I will personally whack Stroud over with a stick for trying one of the most clichéd and terrible plot devices ever.
