There will not be a Black Widow
solo film, which has prompted your "too many" statement. At least not as part of Phase Two. If they happen it'll be part of Phase Three and not start filming till, at the earliest, mid/late 2015.
The first film of Phase Two, IM3, started filming a week or two before Avengers opened if I recall correctly.
