Are you having a laugh ? , this is MacRumors , we are allowed to go completely bananas regarding updates , plus it's also a good bit of fun too
here are my thoughts on MBP update :
i think it doesn`t make sense for apple to
completely redesign the mbp for a little
"speed boost update". most likely, they
will have an event in the next 20-50 days (it doesn`t really matter when)
It does to me and one or two others on here ! , I agree though that I couldn't really see them updating the shell for a minor bump , but then again I don't think this will be a minor bump.
I've been on the phone to his Jobsness and he said the 9th ..or was that just the voices again

, either way if I have to wait longer than the 9th I'll be displeased to say the least ..I'm on a G3 and really could do with a new mini & a Macbook too but will not part with my hard earned for a machine with 2 year old specs , and will struggle to do so for a Macbook as updates are surely round the corner.
then, by MWSF they will either introduce a completely new product or update the mac pro and the displays or maybe both.
probable that something funky will happen at Macworld for sure
then, by the time core i7 comes out for mobile devices, apple will hold a special event and introduce completely new macbook pros.
Or maybe they have some chips on pre release like they did with the iMacs recently
i think apple won`t make a redesign which will be good for only one year, until nehalem mobile is out.
they`ll most likely try to make a redesign in 2009 and stick to it for another 3-4 years.
I agree , a case redesign for only a year is doubtful but it would allow them time to iron out any bugs
