However they are going to be introducing their new Marylebone service a couple of years before the London - Reading - Oxford line is upgraded
Chiltern target date is 2015 - could be May, could be December, will depend on the scale of work required and believe me that scale is pretty large given the state of the embankments much of the way between Oxford and Bicester (hence the currrent 45mph maximum) - Oxford electrics will start December 2016, so hardly a couple of years.

There may have been the option for "local" services operating between Princes Risborough and Oxford - with a new P&R at Wheatley, as well as stations at BMW/Business Park, Littlemore/Science Park/London Welsh Stadium & Redbridge/Kennington.
No prospect whatever. Chiltern took a look at that route (much of which was single track, incidentally) - and steered well clear due to the state of it, the huge gaps around Wheatley due to road building and other developments and the fact that Horspath tunnel is... a bat sanctuary.

Yes, there will be a flat junction at Bicester but Chiltern are the only operator currently so there is less potential for delays
Not when trains have to come all the way from Birmingham to Aynho on shared tracks, where ever more container trains are appearing, and where electrification work will be taking place in the back end of this decade.

Why wouldn't you want to run some trains to Oxford in 1 hour from Marylebone? It is more readily achievable if necessary
And who is saying it is necessary? As I said, the key station for Chiltern is Water Eaton, not Oxford - getting to/from Water Eaton within the hour is the main consideration here, not to Oxford station.
Yes, the exact stopping patterns remain to be determined but the fact of the matter is that even if a train does not stop at high Wycombe, it might stop at Haddenham & Thame instead - there is clear potential for traffic between that station and Oxford and one thing Chiltern are good at is exploiting opportunities like that. Someone I work with drives from Beaconsfield to Oxford every day - driving the M40 may now be an ingrained habit but who knows, if there was a direct train or two at a suitable time?
If Chiltern were determined to go for a 60-minute time then they would surely have said so long ago. The planning of this project and Mainline and timetable development for both went hand-in-hand. If the process had gone as chiltern originally hoped, there would have been a gap of about a year between the two things happening, so the 66-minute timing was not plucked out of thin air. The High Wycombe-Bicester North non-stops take 20 minutes, add on 14 and you get 34. Chiltern's projected HWY-OXF timing is 38 minutes, so not much margin to play with there, allowing for a slow run round the chord line into Bicester Town, even without another stop at Islip/Haddenham, is there?

Chiltern will effectively have a separate standalone route into Oxford and I suspect early arrivals will not be uncommon.
Not when East West opens and there are other passenger trains and freight running (on top of the existing Bicester MoD traffic) they won't. They may get a couple of years of it being their private railway but that will be about it.
