Nehalem is also NOT just another Core 2 like Penryn and might actually make use of an IMC. Otherwise, it becomes just a Gimmick. Also, it'd be pretty stupid IMHO, if Intel added all higher end tech on all processors, even the budget models. I THINK Intel will do just like they did with Hyperthreading (HTT makes a return on Nehalem) and split the line-up feature wise.
