If I was to see a weakness with 360 its simply that the 2007 sales were only a little ahead of 2006 and that on the back of Halo 3... its just to hard that there is anything that will push a big jump.
PS3 might never have a big jump either, but I believe it has more chance than 360 as its performing roughly even but still has its Halo 3 to come (assuming either MGS, FF or GT ever get released that is!) and with BR as choice for next gen high definition media it really is looking better choice. The only gap now is SW library but that will be close enough before the end of this year I think.
Still don't see either catching Wii unless the wind is taken from its sails over time (or it saturates market and PS3 becomes major second choice console).
In the end, unless MS tries yet another quick jump to a different consol, I think 360 can only end in third. The real question is will the PS3 only be a whisker ahead in 2nd or will it start to achieve really big sales and put distance between itself and the 360 over the next three years?
Try to be reasonable... its easier than you think...
