The arcade and the core are exactly the same..... They are simply the regular SKU without a hard drive and maybe a few arcade games included. The original "Core" came with a 512mb memory card, the new Arcades come with 512mb onboard memory. Other than that and regular hardware revisions across all SKU's they are the same so I guess the Arcade should be able to drop to $99. Elite maybe $129 with a $99 price tag after the generation has ended and moved on (like PS2 did recently).
