Nokia brand to be replaced with Microsoft Lumia

If you've seen Microsoft's recent articles about Lumia you know it was coming. The Nokia brand has been phased out by calling the phones just "Lumia" and redirecting Nokia online properties to Microsoft.com. This rebranding effort will expand and soon the lineup will become "Microsoft Lumia".
Lumia is already the de facto face of Windows Phone – it accounts for about 90% of the market. Microsoft has been busy signing up new vendors but they will struggle to gain significant market share as the big names have mostly neglected WP.
Nokia, the company, still exists but as part of the agreement with Microsoft it won't make new phones for at least several more years. Instead it has shifted its focus to things like mapping and, with no exclusivity to consider, it has been bringing its software to Android.
Will Microsoft put its own logo on the devices or will a more restraint Lumia logo suffice? Keep in mind that Microsoft is treading lightly, not to annoy other WP vendors by showing favoritism to its in-house manufacturer.
