My gut says it's not gonna happen. As for just getting some of cupcake, I just don't believe it. Google, htc, and tmobile all want the the g1 to be a success.
Yes they do but also there are mitigating factors, again these are just my thoughts not based on "in the know knowledge" just me thinking about it.
It has already been said that HTC used propriety stuff of their own to make the G1 work with Android and even though they are now on the master branch they are not standard Andorid.
HTC have also stated that they have no control over Android and can't actually say whether Android/T Mobile will release cupcake for it. even though our guess is that they will so that we can beta test it like the rest.
Some big manufacturers have since signed up for the Alliance, now if they are planning to release handset around Q2 then surely they will want all the best features for the newer handsets and not see it all on the older original, I mean what makes people want to upgrade or change when they see better features right? but why upgrade if you can get it on your existing handset? there will be a certain amount of pressure to "hold Back" some stuff to help bring on board these so called manufacturers, also T Mobile may just be touting for exclusives with the newer manufacturers and be seen as the "Android Network of Choice" nothing pulls in the punters more by having an exclusive, just look at the iphone. Now T Mobile would want people to go for the newer and not stick with the older. It's the nature of the beast unfortunately.
Also I know that they will probably sense check and tighten up the code as much as possible but people already moan about not having enough memory on the G1. Now I still haven't seen it written that the G1 will get storage for applications to the SD, so any updates may take up more room. Now this doesn't necessarily mean massive amounts but if we don't get application storage to the SD then they will have to work out just what they can add.
Is the hardware upto all of the potential new features?
I just don't know so thats why I reiterate that it's just my musings really and not a statement of fact and I am happy to be proven (and hope to be proven) wrong.
I agree with the comments that I don't thing it will be an all encompasing update and may just be rolled out in smaller chunks (again so we can beta test it for future handsets) especially if what is linked on this post
LINK is true.
Mark Murphy has echoed my concerns about this update in regards to video recording being included, as from what we understand there are still kinks to work out in the Android CupCake path especially for it to work on the G1, BUT it is what was listed as a feature in the upcoming update according to the internal T-Mobile memo leaked
