It could just be they stopped taking pre-orders for it.
The big JP electronics store I pre-ordered my Halo LE from had only the LE listed when I pre-ordered it awhile back, but last month they stopped taking pre-orders for the LE and listed the regular edition for pre-order and just recently stopped taking pre-orders for it, like 1-2 days ago.The LE and regular version were the same price too. (No legendary edition here)
The Halo LE was the #1 pre-order game(out of all games) on their site, until they stopped taking pre-orders for it, then the Halo regular edition took over the #1 spot, until the pre-orders stopped for it too.
