GET THE GAME!!!
Why waste all wour time on the merchandise, whem you could get what it was created for?
You don't choose two transformers figs over a two disc special edition of the movie.
Get both, Get the legendary first. Then save up your money and buy the zune after. Not too many people I know are going to buy a Halo 3 zune so you should be in luck if they keep it in stock.
The reason you should get legendary first is because there are more chances of losing your chance to get a copy of legendary than losing you chance to get a halo 3 zune.
thanks im gona go calcel my legendary order and get the zune now. and im gona get halo 3 standard cause the helmet will probaboaly collect dust in my room how limited is the halo 3 zune?
