Shame to have the same argument over and over again - to say these games are meaningless flies in the face of any kind of common sense, they are indeed glorified training sessions but training sessions are not in themselves meaningless either, they are the best gauge we have of players' current progress. Progress that could spurt forward or stall, at any time from now - of course..
That's largely my view too. I completely agree that results do not matter, however performances do. Hyypia won't be sending players out in pre-seasons with the instruction to just run about a bit, not to get injured and play as if they possess limited technical ability.
Additionally players will be trying to impress the new manager, and attempting to put in performances that give them a chance of a starting eleven position on August 9th.
