Their last results do not support that idea, the amounts they are having to spend are not in line with level of sales. Nokia will go under if it has to keep burning cash at the current rate in order to make an impact.
WP7 was going really well for Nokia, and sales stats improving all the time, until Microsoft went and ^&*(^& them over by announcing that WP7 devices wouldn't be updated to WP8. I'm actually supprised they are still selling at all.
The latest results obviously reflect this.
