I used to LOVE the NFS series, but I haven't actually 'liked' a NFS title since Pro Street.
Most Wanted was great because COPS returned.
Carbon was great because you raced with a 'crew' and the new 'canyon' races.
Pro Street was great because it offered more realistic drag racing.
Everything since Pro Street, barring the ability to be a cop in the new Hot Pursuit, was pretty much crap.
If 'The Run' is anything like the past four (or five if you count NITRO) games, you'll be able to find it in the $20 bin within 3 to 4 months after release.
