p/e ratio

Would like some thoughts and comments on this:
I note the following P/E ratios:
CER. 3.8
Dexus. 9.5
GPT 19.1
Stockland 13.8
CFS. 8.39
Lend Lease. 12.1
Mirvac 20.3

Given that CER (post US sale) will be a relatively "normal" A-Reit, was
wondering if we should expect our P/E multiple to eventually match
that of our peers. If this is the case, can I conclude that we should see
the CER share price rise 3-5 times the current?? Comments please Defab, Nursery...
Cheers
