There's going to be a lot of excitement today as tons of PlayStation Vita videos go up all over the internet, looking to cover what Sony hopes will be a smashing successor to the PlayStation Portable. If you're a Sony fan, you're probably not swayed too much by the arguably high asking price ($250 plus the price for a memory card)... but for those who are on the fence, take these things into consideration that were discussed this weekend on Twitter:

1. Early glut of supply: Despite rumors stating that preorder numbers were high and fears that possible shortages of Vita hardware may result from demand, we're seeing reports that supply is surpassing demand. This trend seems to echo what we saw for the Nintendo 3DS when it launched, as Sony and Nintendo looked to reverse shortage situations from past hardware launches. Unfortunately, the adjustment was too significant for Nintendo and could be the same for Sony. Putting too much hardware in the pipeline at launch gives consumers a reason to play the waiting game instead of wanting to buy immediately in order to take advantage of short supply. Worse yet, anecdotal evidence from gaming press in Japan seemed to indicate that interest in Vita had waned and 3DS interest had been growing. We'll have to see how Week One numbers bear out, but this potential trend is one to watch.

2. Poor battery life: There were indications that the Vita battery lasted for two hours before full discharge during an Uncharted play session. This anecdotal evidence was taken down soon after and replaced with a statement about needing field testing, but the battery life now becomes an even hotter topic of discussion. Will consumers need to adjust brightness and fiddle with Wi-Fi settings to maximize the battery life to the point of lasting longer than 120 minutes? How will other games affect battery life? Read impressions and review pieces carefully to find info about battery life, because chances are reasonably good that we'll see the same issues crop up in other territories, as well. Perhaps two hours is long enough for some, especially if there's an outlet nearby, but even the alleged issues with the 3DS battery weren't this bad.

3. Possible dissatisfaction: This tweet (and picture) seems to indicate that Vita games were quickly being turned around for second-hand sales. Considering that it had only been a couple of days since launch, it could be bad for perception. On the flip side, those games may also be less-than-stellar offerings in the Vita's launch library. Still: Used games so quickly after a platform's release never looks good. Link this strike with strike 1 above, and it sends a message that there's a lack of interest and/or dissatisfaction with Vita at launch which could affect sales in the near-term. 3DS had problems selling without many games at launch, to go along with the high price tag. If Vita underwhelms at its launch price point with a stronger games lineup, the argument about price being too prohibitive becomes even more valid.

Keep in mind that these are launch trends and not necessarily indicative of the Vita's future on store shelves... but these strikes should also be considered when viewing the overly-enthusiastic videos and articles that address the arrival of the Vita over the coming days. If any (or all) of these factors proves correct, then Sony will be more significant hurdles to clear when the Vita lands in the US in February.
