I wouldn't trust just one sight's opinion. besides I think it make more sense for this to occur:
August-New MB and MBPs (although I wouldn't mind this tuesday: July 29th)
September-New Ipods (after the 15th so the college kids still get the old ones)
and then somewhere in there or in October they'll release their new mystery tablet or whatever. Ipods are most definitely coming out after the 15th of september due to the college deal. So why would apple release a new full line of ipods AND new MBs and MBPs all so close to each other. While at the same time losing laptop sales to college students on the fence about getting a mac who decide to buy the recently updated PC instead of the 6 month old mac. Apple's got to release the new MBs and MBPs before september or that's bad business.
Sounds like a good possibly to me.
