There's an interesting amount of confidence in what HS2 will achieve - there's a lot of it I think is far from certain.
Firstly, I'd suggest users are putting far too greater value on time. Even on relatively short distance journeys, plenty of customers already would rather save a few quid at the expense of 30 mins or so (eg, from my neck of the woods: Manchester-Leeds, Liverpool-Manchester, Leeds-York). The deciding factor will be the price point that HS2 enter the market at. It wouldn't surprise me at all if its relatively expensive, and many customers will opt for a longer journey.
Then there's the loss through connections. I've always been quoted the figure of 80% loss of customers as soon as a connection is introduced (thats from an Arup engineer who specialised in transport projects). To suggest someone would double back from as far a field as Leamington is a bit of a moot point once you consider the minimal journey time savings and increased expense. I'd suggest even the people of Solihul would generally stick to the direct, slower service, over the faff of a cross city change. That is, unless of course, HS2 services come into the market at a reasonable price point.
It's also fair to say that Chiltern obviously see the requirement for a more intercity element to their operation, there have been numerous options over the years to replace the 67s/68s but they have never been taken. I'd argue the future market is there, even discounting London-Birmingham flows, for a limited stop semi-express (Wycombe, Bicester, Banbury on the South end). Clearly that's less express than was, but still more of a regional express than a commuter run. I'm not saying a 168 wouldn't be suitable for this - merely that I'd expect a market to still exist, and this could be well served by a more intercity type unit.
