Will this Warranty plan work?

[GearsOfWar]

I was wondering if ppl who got their 360 last yr with 1 or 2 yr store warranty will be able to exchange to the Jasper model.

what if all the 20GB model is sold out? will they exchange it to 60GB model?

Another question is...
if I get Jasper with 1~2 yr store warranty and Valhalla (CPU+GPU into one 45nm~!)
comes out, will the store exchange it into Valhalla model even if they look different such as slimmer look?



If above works, here are my plan
Get Jasper with maybe 1 yr warranty assuming valhalla comes out within 1 yr
If it gets RROD, send it to MS, not to the store.
MS will send me the model back to me (hopefully, item number on the back is still the same)
and after 1 yr, if i get RROD again, exchange it into valhalla.
