yes man
ofcourse there will be new sockets

sandy bridge processors wil come out.
some of those processors are very low power....like a normal dual core takes now.
also there focussing on more cores.
they have a locked base lock...so overclocking isnt gonna work very well..
if you want to overclock with those cpu's...take a cpu with a K in it
they are not really that much faster atm then a 1366 i7.
the difference is a other team designed this then the i7 team...
ofcourse it will become faster on the new socket anyways.
hexa and octa cores will only come out on socket lga2011 tho

and ofcourse motherboards support quad channel ram.
update of socket 1165 = 1155
update of socket 1366 = 2011 or the year it will come out.
if you wonna upgrade...you dont have to wait perse on the newer systems....it wont help you game faster anyways...well, not with tf2 anyways
oh btw: new cpu's has very strange names...
for instance: Core i7-2600K is a 3,4GHz (3,8GHz)
that new name system of intel makes things rather complicated...
