May be eth will grow till the last DAO day (it will be HUGE panic buy on the last DAO day) = fear of missing something (human nature)
As illogical as this may seem, especially since The DAO has a 28 day buying window and the first 14 of those will be at the cheapest price (meaning the last days are most expensive), I expect you will be proven right as people will just have to get in before its too late.
