"Overland trains to accept Oyster"

One tiny problem with that statement, taking my local area as an example......

Oyster PAYG is being extended to Grays from both Upminster & Rainham (that's on c2c if you don't know). Upminster & Rainham, despite the Essex postal address, are both in London's Zone 6 and so are certainly able to count towards a Travelcard cap. All of the stations that join the scheme in 2010 (Ockendon, Chafford Hundred, Purfleet & Grays) are in Essex proper, outside London, and are therefore outside the zones and the Travelcard capping system.

So what appears at first glance as a welcome move for stations up to Grays, is actually about as much use as a chocolate teapot.

Now if the Travelcard zonal system were extended to Grays (and thus bringing with it the ability to use my staff pass ;D ;D), it would certainly look like a better proposition....

EDIT: in fact given that TfL has three bus routes in my area (347 to Ockendon station and 370 & 372 to Lakeside (Chafford Hundred)), on which Travelcards (and my staff pass) are accepted, it really ought to make a lot of sense to extend the Travelcard boundary to Grays - and perhaps even restore the 370 back to Grays too!!
