As Sony never called the current PS3 model "slim" I do think that they will release a "slim" version, maybe even this holiday.
But I wouldn't expect to see it announced at the Gamescom, because it wasn't even sure Sony would attend it until some weeks ago. Such a big announcement (and likely a market start same day/same week) is planned month in advance, so Sony's reserved attitude makes me doubt they planned it for GC.
Then again it could have perhaps been a strategy to bargain for the lowest prices as there were indications that Nintendo and MS wouldn't attend, putting pressure on the convention management to atleast secure Sony's presence.
