Damn you people even quoting these!
I'll just quote the post i made in MR forums about this same topic.

Android, WP7, IOS(!) wont be seeing light of day inside Nokia phones for over 2 years no matter what.
Really, Nokia have made agreements with likes of Qualcomm, TI, Broadcom etc. to make chips for Symbian and MeeGo 2 years ago that we will just start seeing.
New qt based services meant for MeeGo and S^4 must be nearing the end, Nokia have hired and still is hiring people to work around Symbian, Qt and MeeGo, plus lots of b2b agreements we have no idea about made behind the closed doors.

You never know how will things look in 2 years time and what if WP7 would actually make sense then so i wont say this all wouldn't ever happen, but for now there's no way imo.
