There are currently 58 S Stock trains being delivered by mid 2012. Then, according to the upgrade plan, a new signal and control system will be installed by 2018 which will allow LU to "run many more trains". Does that mean that 58 trains won't be enough? Or will the new control system allow the existing fleet to run faster, or more reliably, meaning better productivity from the initial fleet of 58?

The latter. The trains that are delivered will be able to run faster and closer together meaning LUL will get more train for their money, without actually needing more trains!

And of course 58 trains is more than the Met had with 'A' stock, so it's a bit of both.

For a long time, yes, but total A stock ordered was 58*8 car trains; 31 A60 and 27 A62.
Interesting to note that despite the massively-enhanced services promised post signalling upgrade to keep seating capacity per hour the same, the same amount of trains as needed 60 odd years before then.
I can't quote work out where the extras come from, especially considering a lower top speed, and far reduced non-stopping patterns. The one reduction of note though compared to then will be for Chesham; at peaks it had throughs and shuttles giving 3/4tph.
One wonders if keeping seats per hours the same was actually a con...

I think the way the S stock are currently performing, or should I say not performing, we might see another new stock by 2018 ;D

As there will be a new timetable, once the resignalling is complete, who is to say what the off-peak stopping patterns will be. You never know, they might actually replace Harrow North Junction with something more reliable and reinstate the off-peak fasts. Don't forget that in more recent times, the A Stock was also being used on the East London line, so the Met line S stock fleet will several trains larger than the A stock fleet which was available for many years. |

Using more or less the same number of trains as today, from the December timetable the service will see the following increases:
Uxbridge Branch frequency increased from 10 minute to 7-8 minute service.
Stations from North Harrow to Northwood will see an increase from a 10 minute frequency to 7½ minutes.
Increased Met frequency in the city with direct trains to Amersham and Chesham.
Now we all know everyone's views on this timetable - and there are obviously reductions in certain services (notably Croxley and Watford). However, this demonstrates that you don't always need more rolling stock to achieve increased services.
Taking December's timetable another step, and reducing layovers at termini slightly, and you could (in theory) increase frequencies further without using extra stock.
