Is Windows 8 [or 8.1] a Service Pack #2 for Windows 7…in disguise ?

I found windows 8.1 preview very impressive,

perhaps a little too much,

I indeed think that the era of servicing the OS’s is over, specially by Micro$soft, the hassle of windows 8 could be avoided by simply issuing a service pack to the ROBUST Windows 7 Platform !!
