Paul to answer your question you made some good points.A friend bought a R1200S after trading in his 03 Boxercup and I got to ride it for a weekend.
Anyways you are right when you say the F800S will do anything the R1100S does.I think it is even a little faster due to lighter weight.Only the bags are a minus which are smaller compared to the R1100S which can be a tight fit on a touring trip for 2 people.But the F800 feels to generic almost japanese to me.I would miss the boxer engine.
The R1200S I like a lot.But the difference to the R1100S is not as big as some people want you to believe.It really comes down to two things.You either get the additional top end rush and 15mph higher top speed with the R1200S or the anmeneties like bigger bags,2 up ability and practical center stand with the R1100S.It's is a personal decision which is more important to you.The R1100S is also a hair more comfortable with higher bars and better padded seat.Too bad that you have to make that decision and can't have both with the new bike.The 130 mile + 40 mile reserve tank range is to small on both...
Anyways with the "real" HP2-S sportboxer introduced this weekend on the 28th in paris it would only make even more sense not to have to make those decision between the advantages that the R1200S or the R1100S,anymore...
Like I said,keep your fingers crossed...
Until then, for me at least and looking at the sales obviuosly a lot of other riders ,too, the additional power of the new one is not persuasive enough to give up on the pratical advantages of the old one.And yes the F800S/ST are great bikes but for a boxerfan too normal/generic/japanese/flavourful enough...
PS:To turn the question around, what does the R1200S better than the R200S-HP2-Sport?It has panniers...

?
But the HP2-S will have an 23 litre "endurance-tank".What a wasted opportunety...
