WPCentral posted a news story that Microsoft registered domains using Sony brand

Could Microsoft's recent domain acquisition signify a possible future collaboration between Sony Ericsson and Microsoft? It's surely debatable, but the domain names are so vague that it could cover a joint-venture between Sony itself and Microsoft (in entertainment etc.), as opposed to Sony Ericsson with Windows Phone 7. See the domains for yourself, sony-microsoft.com and microsoft-sony.com (both redirect to Bing SERPs), not really 'WP7 friendly' right?
Forum users at Neogaf discovered the domain names that were registered to Microsoft through Corporation Service Company (CSC), a corporate identity protection firm. The replies in the thread contain ideas that range from the software giant possibly taking over Sony (or vice versa), a Sony Vs Microsoft fighting game, Microsoft trolling, or -- of course -- Sony Ericsson WP7 handsets.
