Assuming no one from Amiga Inc steps in to claim it, Amiga.com will go to auction. You have to realise that while it is worthless as a computer domain the name "Amiga" means Female friend in both Portuguese and Spanish. It could easily be worth a small fortune to a dating service or the infamous EspaƱol Lesbianas.
My guess: minimum €25,000, maximum €250,000.
This is big, a real word, in a big real language, in dot com.
