I am seeing in some other countries, where you have to be signed in to use Instant (and thus Instant is not yet the default), that the singular form in some searches is shown before the plural. These are searches where I know the AdWords Tool reports exact search volumes for the plural are higher, though not by as wide a margin as in the US. It will be interesting to see, as the suggestions evolve, whether these will shift. Currently, the plural isn't even shown in proximity to the singular, so it may be hard for some searchers... those who are 'obedient' to the list... to make a choice.

I should mention, incidentally, that the Suggest and the Instant suggestions are not the same... they can't be since there are only 5 Instant suggestions vs 10 Suggest suggestions... but they seem to be picked in the same order from the same list. I haven't checked the details carefully, but it seems that the first 5, minus near redundancies, are used.
